wrangler dispatch namespace: script not found

wrangler dispatch namespace: script not found

TL;DR

The dispatcher references a script name that is not uploaded to the namespace. Check the uploaded scripts list; the name is misspelled, was never uploaded, or was removed. Names must match exactly.

wrangler dispatch namespace: script not found

Steps

1. List the scripts in the namespace and compare names exactly. Expected: The missing name is confirmed.

2. Check for typos, case differences, and stale references. Expected: The mismatch is found.

3. Upload the missing script or fix the reference. Expected: The dispatch succeeds.

4. Keep the dispatcher config and the uploaded scripts in sync (ideally generated). Expected: Drift stops.

5. Verify the dispatch end to end. Expected: The routing works.

When to use

• dispatch fails with script not found
• the namespace was just set up
• scripts were renamed

When not to use

• the script exists (check for a namespace mismatch)
• the error is on the dispatcher itself (different problem)
• using workers directly (no namespaces involved)

Tool compatibility

• wrangler
• Workers dispatch namespaces

Variant phrasings

• "dispatch namespace script not found"
• "worker dispatcher script missing"
• "namespace script not found"

Why it happens

Dispatch namespaces route to named scripts, and the names are exact-match. A rename, a missed upload, or a typo breaks the route. The namespace does not fuzzy-match; it fails. The fix is keeping the name list and the uploads in agreement.

Edge cases

• names are case-sensitive; check exactly
• deleting a script breaks dispatchers silently until the next call
• generate the dispatcher config from the upload manifest
