churn agent failed to rotate the Mixpanel service account secret value usage export returned 401 for three straight...

Not specified by the original author.

TL;DR

Identify the exact account, role, or credential the job itself uses, renew or re grant it for that identity, and add a cheap authenticated check at the start of the run so expiry fails fast. Start in the Mixpanel project settings, the import API response log, and the Lexicon, work on one affected item, and prove the fix there before running the full set. Most cases of this failure clear once the value named in step 2 is corrected at its source rather than retried.

churn agent failed to rotate the Mixpanel service account secret - usage export returned 401 for three straight nights

Use this when

• You see this exact message or symptom in Mixpanel: churn agent failed to rotate the Mixpanel service account secret - usage export returned 401 for three straight nights
• One run, record, build, or object is affected and you can name it
• A retry without changing anything reproduces the same text

Not for this skill when

• Mixpanel fails with a different message and none of the signals here appear
• Nothing has failed yet and you are doing first time setup or general planning
• Every service from this vendor is down for all users, which is a vendor outage to wait out first

Steps

1. Reproduce the failure once in the Mixpanel project settings, the import API response log, and the Lexicon and search the log or history for the exact text in the block above, recording the time, the workspace or project, and the one object it names. Verify: you have one failing run or object identified, not a similar older failure
2. Inspect the import payload, the project credential used by the job, the distinct_id values, and the JQL or cohort definition, and check the job identity, its roles or scopes, the credential expiry date, and the start of run authentication check. Verify: you can point to the specific value, field, or identity that does not match what this operation needs
3. Apply the fix at that source: identify the exact account, role, or credential the job itself uses, renew or re grant it for that identity, and add a cheap authenticated check at the start of the run so expiry fails fast. Verify: the corrected value or setting is visible in Mixpanel itself, not only in a local config file
4. Re-run the original operation on the single affected item first: re-import a one day slice through the import API, then re-run the scoring query on that slice only. Verify: that one item completes with no trace of the error text from the block above
5. Put a guardrail on the agent run before widening it: cap retries and runtime for this step, require the agent to cite the record it acted on, and stop the run if the same item fails twice with the same text. Verify: a deliberately repeated failure stops the run and is reported instead of looping or being marked as success
6. Check the downstream result a user or the next job would see: the event volume for at-risk accounts in Explore and the updated risk list after scoring. Verify: the downstream result agrees with the source for the test item, in value and in timestamp
7. Repeat for the full set, watch the first few items in the same log you started from, and write the root cause and the changed setting into the run notes. Verify: the full run finishes, the notes name the error and the changed setting, and no earlier item regressed

Variant phrasings

churn agent failed to rotate the Mixpanel service account secret - usage export returned 401 for three straight nights

The subject-first phrasing of the same failure. The fix is the same, start at step 1 and confirm the object the log names.

Mixpanel version of this failure

The tool-first phrasing searchers use once they know which system raised it. It is the same underlying problem, not a separate bug.

Why does churn agent failed to rotate the Mixpanel service account secret - usage export returned 401 for three straight nights keep happening after a retry

The repeat-occurrence phrasing. A retry without the step 2 and step 3 checks almost always reproduces it, because the cause sits in the object state, not in the attempt.

Compatibility: Mixpanel import API and JQL, service account authentication, current Mixpanel project settings. The steps assume you can read the job or build log and change the named object in Mixpanel.

Why it happens

In Mixpanel, this failure usually means the identity the job runs under is not the identity the operator tests with, or its credential stopped being accepted mid run. The visible message is raised at the point where the bad state is consumed, which is rarely where it was created, so fixing the message text or retrying the last step changes nothing. Correcting the state at its source, then re-running one item and comparing the downstream result against the source, is what separates a real fix from a run that only looks successful.
