alert routing failure error Slack webhook returned 404 anomaly alerts lost

Not specified by the original author.

TL;DR

Fix this in Slack by acting on the exact message first: recreate the routing credential in the receiving service, update it in the sending config, and send one test alert end to end. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

alert routing failure error Slack webhook returned 404 anomaly alerts lost

Use this when

• The operation in Slack fails with this exact message: alert routing failure error Slack webhook returned 404 anomaly alerts lost.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in Slack, and copy the full message plus the item, user or metric involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: recreate the routing credential in the receiving service, update it in the sending config, and send one test alert end to end. Verify: confirm the test alert arrives in the target channel or incident list.
3. Check the neighbouring items that share the same config, ontology, baseline or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result counts, decisions or alerts against the source in Slack so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in Slack on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

Routing keys and webhook URLs are revoked on rotation or channel deletion; the detector keeps sending to a dead destination and alerts are lost silently.

How to fix: alert routing failure error Slack webhook returned 404 anomaly alerts

The how-to phrasing for the same failure in Slack. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

Slack troubleshooting for this failure

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

Compatibility: Slack at current versions, plus the platform API or console the query names; no extra tooling beyond a text editor and the source system access needed to verify counts.

TL;DR

The alert call is fine; the team's Slack integration is not connected on the W and B side: an admin must connect Slack in the team settings and authorise the workspace before any run alert can deliver. Verify by sending a test alert from the team settings, then re-run the alert call; code-side changes cannot substitute for the missing integration.

wandb alert failed error 'Slack integration not configured for this team' failure

Use this when

• The run or call fails with this symptom: Slack integration not configured for this team from a wandb alert call.
• You are working on a wandb run raising alerts to a team Slack channel and the failure repeats on the same run or configuration.
• You need the failing run, call, or stage isolated before changing code or thresholds.

Not for this skill when

• An alert addressed to a channel the integration was never invited to, where the fix is inviting the app to that channel.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Open the team settings and check whether Slack appears as a connected integration. Verify: the integration state is confirmed
2. Have a team admin connect Slack and authorise the intended workspace and channel. Verify: Slack shows connected for the team
3. Send the settings page's test alert and confirm it lands in the channel. Verify: a test message arrives in Slack
4. Trigger the run's alert again and confirm delivery with the run link attached. Verify: the real alert posts successfully

The setup phrasing.

Compatibility: Weights and Biases alerts and Slack integration

Why it happens

Alerts deliver through a team-level integration that is configured once by an admin, separate from any run or user setting. Code can be perfectly correct and still fail every alert until that organisational step exists.

Edge cases / pitfalls

• Personal Slack connections do not cover team alerts; the team integration is the one the alert path checks.
• After reconnecting Slack, channel memberships reset; re-invite the app to private channels.
