expansion signal detection failed error usage spike not flagged failure

Not specified by the original author.

TL;DR

Fix this in the expansion signal detector by acting on the exact message first: replay the missed product event window for that account after checking ingestion lag, and recalculate the spike against a 28 day median baseline instead of a mean that the spike itself inflates. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one record, then rerun the full scope and reconcile the counts.

expansion signal detection failed error usage spike not flagged failure

Use this when

• The operation in the expansion signal detector fails with this exact message: expansion signal detection failed error usage spike not flagged failure.
• The same failure repeats on retry with unchanged inputs.
• A run, import, export or alert is blocked until this item completes.

Not for this skill when

• The message is a permission or platform outage notice. 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 the expansion signal detector, and copy the full message plus the record, account or list involved into the run notes. Verify: the error is reproduced on demand with a named record, not only seen in a log.
2. Apply the specific fix for this error: replay the missed product event window for that account after checking ingestion lag, and recalculate the spike against a 28 day median baseline instead of a mean that the spike itself inflates. Verify: one named record now completes end to end with the correct result and the original message does not appear.
3. Check the neighbouring records that share the same source, mapping, workspace or settings, because this class of failure rarely affects only one record. Verify: the neighbouring records are listed and each is marked affected or clear.
4. Compare the result counts, fields or alerts against the source in the expansion signal detector 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 the expansion signal detector 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 record so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

The detector compared the spike to a mean pulled up by the spike itself, or the events arrived after the scoring run, so no threshold was crossed at scoring time.

How to fix this failure in the expansion signal detector

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

Troubleshooting this failure in the expansion signal detector

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: the expansion signal detector at current versions, plus the platform API or console the query names; no extra tooling beyond the source system access needed to verify counts.

TL;DR

Fix this in expansion task agent workflow by acting on the exact message first: give each expansion task an idempotency key built from account plus usage spike date, store created task ids in a progress file, skip accounts already tasked in this spike, and halt the run when the same account is offered twice in one pass. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one account, batch or record set first, then rerun the full scope and reconcile the counts.

3. Check the neighbouring accounts, signals or jobs that share the same config, schema or source, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in expansion task agent workflow 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.
5. Compare the result counts, scores or status against the source in expansion task agent workflow so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
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

Hourly runs with no record of tasks already created treat the same spike as new every hour, because the spike stays visible until the underlying alert clears.

Edge cases

• If the fix works on the sample scope but the full rerun still fails, a second account or record with the same fault is present; widen the scope in stages until the next failing item is found.
• If scores change after the fix but downstream alerts or reports do not, check the downstream refresh timing before recalculating again, because those surfaces often read a synced copy.
• If the source information itself is missing for the affected accounts, record that as a source gap rather than scoring the accounts as zero.

Fix this in usage metering by acting on the exact message first: separate event time from ingestion time in the metering pipeline, mark the backfilled batch so growth alerts ignore ingestion spikes, recalculate organic growth from event time only, and verify the backfill day no longer raises an expansion alert. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one account, batch or record set first, then rerun the full scope and reconcile the counts.

Why it happens

Backfilled events all land on one ingestion day, and a growth check reading ingestion time sees a single day spike that never happened in real usage.
