scraper failed on Snowflake usage query result returning empty results f

Not specified by the original author.

TL;DR

Fix this in Snowflake usage scraper by acting on the exact message first: run the Snowflake usage query directly and save its result to a file, check the warehouse and schema names after the schema change, fix the query to the new names, and backfill from the saved result instead of the empty scraper output. 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.

scraper failed on Snowflake usage query result returning empty results for backfilling usage history error scraping failure

Use this when

• The operation in Snowflake usage scraper fails with this exact message or symptom: scraper failed on Snowflake usage query result returning empty results for backfilling usage history error scraping failure.
• The same failure repeats on retry with unchanged inputs.
• Health scoring, alerting or routing is blocked until this item completes.

Not for this skill when

• The message is an 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 quality. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in Snowflake usage scraper, and copy the full message plus the account, measure or job involved into the run notes. Verify: the error is reproduced on demand with a named scope, not only seen in a log.
2. Apply the specific fix for this error: run the Snowflake usage query directly and save its result to a file, check the warehouse and schema names after the schema change, fix the query to the new names, and backfill from the saved result instead of the empty scraper output. Verify: the smallest failing scope now completes, or the named account, measure or job behaves as the fix predicts.
3. Check the neighbouring accounts, measures 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 Snowflake usage scraper 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 Snowflake usage scraper 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

A scraper wrapping an old query returns empty results after a schema change, while the underlying usage is intact under the new schema names.

How to fix - scraper failed on Snowflake usage query result returning empty results for backfilling usage history error scraping failure

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

Snowflake usage scraper 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.

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.

Compatibility: Snowflake usage scraper 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 warehouse usage export scraper by acting on the exact message first: check the warehouse usage export the scraper requested, confirm its date window and schema still return rows in a direct query, fix the export query if the schema moved, and fall back to a direct warehouse export when the scraped export stays empty. 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

An empty scraped export usually means the underlying query window or schema changed, not that no usage exists to sync traits from.

TL;DR

Fix this in at-risk routing agent workflow by acting on the exact message first: verify the usage stream query still matches live event names, check the scraper time window covers the period the drop occurred in, and if the stream is genuinely empty for an account treat that as the at-risk signal itself and route it instead of failing the run. 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

An empty usage result can be a scraper window or event name fault, or real zero usage; distinguishing the two matters because zero usage is itself a routing reason.
