JWT expired

Not specified by the original author.

TL;DR

Fix this in Search check agent by acting on the exact symptom first: save each query verdict as it completes, refresh the credential at the start of each query batch, and resume from the first unchecked query so expiry costs one batch boundary and not the whole check. Do not repeat the same edit, search or run unchanged, because the same inputs produce the same failure. Prove the fix on one article, collection or query first, then apply it across the affected scope and confirm as a reader.

Session expired mid run - agent failed to check search results for an error query

Use this when

• Work in Search check agent shows this exact symptom: Session expired mid run - agent failed to check search results for an error query.
• The same symptom repeats after a retry with unchanged inputs.
• Readers or support agents are blocked until this item is corrected.

Not for this skill when

• The help center platform itself is down or returning outage notices. Resolve that first, then return here if this symptom remains.
• The content is correct and you only want a style or tone rewrite. That is an editorial pass, not this fix.

Steps

1. Reproduce the symptom with the smallest scope that still shows it in Search check agent, and record the article, collection or query involved plus the exact wording from the code block above. Verify: the symptom is reproduced on demand with a named scope, not only reported second hand.
2. Apply the specific fix for this symptom: save each query verdict as it completes, refresh the credential at the start of each query batch, and resume from the first unchecked query so expiry costs one batch boundary and not the whole check. Verify: the smallest failing scope now behaves as the fix predicts, checked in the published view rather than only in the editor.
3. Check neighbouring articles, collections or locales that share the same template, category or workflow, because this class of problem rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Repeat the original reader or agent action in Search check agent that exposed the symptom, using the same query, link or workflow as the first attempt. Verify: the action completes and the original symptom does not appear.
5. Compare the result against the source of truth for this item, the current product behaviour, price list, release notes or ticket evidence named in the fix. Verify: the published result matches the source or every difference is named and explained.
6. Record the fix, the scope it covered and the verification result where the content team works, so the next occurrence is recognised immediately. Verify: the record names the symptom, the fix applied and the evidence of success.

The how to phrasing for the same problem in Search check agent. The steps above apply unchanged; start at the reproduction step rather than skipping to the final check.

Search check agent troubleshooting for this symptom

The symptom first phrasing used when the full message is hidden. Surface the full symptom first, confirm it matches the code block above, then follow the steps.

Why it happens

Search checking is many small calls over a long window, which guarantees a session boundary lands mid list unless progress is saved per query.

Edge cases

• The symptom appears in one locale, collection or audience view only. Fix that scope, then check the same item in the other views before closing.
• A cached or indexed copy keeps showing the old state after the fix. Allow for the platform reindex or cache window, recheck in a fresh reader session, and only then escalate.
• Two items have near identical titles. Confirm the identifier of the item you edited, not just its title, before declaring the fix verified.

Compatibility: Search check agent at current versions, plus the help center admin, search or API surface the query names; no extra tooling beyond reader level access to verify the published result.

TL;DR

Supabase JWTs expire (user sessions default to one hour), and an expired token fails every call until it is refreshed. Catch the expired-token failure, call refresh_session, retry the request once, and track expiry so you refresh before it lapses. Never hardcode a long-lived key to dodge this; handle the refresh.

Error

JWT expired

Steps

1. Reproduce and confirm the failure is expiry, not a bad key. Decode the token payload (the middle segment of the JWT) and check the exp claim against the current time.

Expected output: exp is in the past. If the token never parses, it is malformed or the wrong key, which is a different fix.

2. Refresh the session and retry the failed call once:

session = supabase.auth.refresh_session()
result = supabase.table("events").select("*").execute()

Expected output: the refresh returns a new session and the retried query succeeds. One retry is enough; looping retries on a still-expired token just burns calls.

3. Wrap data access so expiry is handled in one place instead of every call site:

def query_with_refresh(fn):
    try:
        return fn()
    except Exception as e:
        if "JWT expired" in str(e):
            supabase.auth.refresh_session()
            return fn()
        raise

Expected output: transient expiries self-heal. Genuine auth failures (revoked user, wrong key) still raise.

4. Track expiry proactively for long jobs: read exp from the session at startup and refresh when the remaining lifetime drops under a few minutes, rather than waiting for a failure mid-run.

Expected output: long-running pipelines stop dying halfway with JWT expired.

When to use

• Supabase calls fail with "JWT expired" after working earlier
• Long-running jobs or agents die partway with auth errors
• You rotated anon or service keys and old tokens are in flight

When not to use

• Every call fails from the start (that is a wrong key or wrong project URL)
• The error is "invalid JWT" rather than expired (check the key value and format)
• Row-level security blocks the query (that returns a policy error, not expiry)

Variant phrasings

anon key itself expired after rotation

You rotated keys in the dashboard; clients holding the old key get JWT expired. Ship the new key and refresh sessions.

JWT expired only in one environment

That environment has a stale key baked into its config. Compare the key against the dashboard value.

Why it happens

Supabase auth is stateless JWTs: the token carries its own expiry and the server rejects it once exp passes, with no grace period. Sessions are meant to be refreshed, not immortal. Anything long-lived (a pipeline, an agent loop) will outlive its first token unless the code handles refresh.

Edge cases

• Clock skew between client and server can make a fresh token look expired; sync the clock before debugging further.
• The refresh token can also expire after long inactivity; then the user must sign in again, so fail loudly with that instruction.
• Service-role keys do not expire the same way; if server-side code uses one, expiry handling belongs on the user-session path only.

TL;DR

Upgrade your Nhost JS SDKs (@nhost/nextjs, @nhost/react) to the release containing the fix. Intermittent 'JWT token expired' errors in Next.js SSR (both client and server, with getNhostSession) were an SDK bug in the token refresh path, already fixed upstream.

Steps

1. Intermittent 'JWT token expired' errors in Next.js SSR (both client and server, with getNhostSession) were an SDK bug in the token refresh path, already fixed upstream. Upgrade your Nhost JS SDKs (@nhost/nextjs, @nhost/react) to the release containing the fix. If you're pinned to an old version and see random auth expiry under SSR, update first before debugging your session code.

When to use

Use this skill when you run into "Next.js SSR: intermittent JWT token expired errors".

When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.

In gh:nhost/nhost#2348, the issue was: I'm investigating integrating next + nhost with SSR enabled (pages router). Setup: [NhostProvider] + [NhostApolloProvider] + getNhostSession from nhost/nextjs. In general it works really well. But sometimes (and it's not clear when and why) I receive errors about JWT token being expired, both on client and server.. The verified answer: Intermittent 'JWT token expired' errors in Next.js SSR (both client and server, with getNhostSession) were an SDK bug in the token refresh path, already fixed upstream. Upgrade your Nhost JS SDKs (@nhost/nextjs, @nhost/react) to the release containing the fix.
