Fixes the synthetic data agent workflow failure agent broke parsing multi table relational schema - foreign keys dropped by applying the specific fix in the steps, proving it on one small scope first, then rerunning and reconciling counts. Use when this error blocks generation, validation or export. Not for platform o…
Fix this in Enrichment agent by only report surge topics that appear as rows in the provider export for that company, join intent claims to the export by company domain, and remove every topic claim with no matching export row. Use when this exact error blocks an enrichment run, import or sync. Not for a platform outa…
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. Use when this health scoring, alerting or sync failure repeats on retry and blocks …
Update the usage sync column mapping for the renamed Snowflake column, point the sync at the new column name, replay the usage loads missed since the schema change, and verify a named account usage matches a direct warehouse query. Use when this health scoring, alerting or sync failure repeats on retry and blocks acco…
Add a null filter or a default value for the custom object field used in the Gainsight Data Designer aggregation, preview the fetch step to find the records carrying the null, fix or exclude those records at source, and rerun the aggregation job to completion. Use when this health scoring, alerting or sync failure rep…
Strip comments before you split statements: Trino information schema output with multiline comments breaks naive parsers that split on semicolons or read line by line, so parse the result set as rows from the driver instead of scraping formatted text. Use when an agent workflow reading Trino information schema through…
Ground lineage in executed SQL only: the agent reported column lineage from a query it drafted but never ran, so build lineage from query history or the compiled SQL of runs that actually executed, and mark drafted SQL as unverified. Use when an agent workflow producing column lineage for audits or impact analysis. No…

Compare the key types field by field and cast keys to one agreed type (for example string on both sides) at ingestion, because the drift check failed when the entity key is an integer in Hopsworks and a string in serving, so identical customers never match and the comparison reports phantom drift. Use when you see thi…
Vectle found the following relevant skills: - agent loop detected: agent retries failed Hopsworks insert with same duplicate primary keys error - agent failed to compare online and offline Hopsworks values after key encoding parse error
Problem outcome: unknown

Pin the reader schema and convert deliberately: the producer upgrade started promoting Avro longs to doubles, so the type check sees a new physical type, and the fix is an explicit conversion at ingestion rather than letting promotion change values silently. Use when an Avro based feed consumed by a warehouse or lakeh…
Fixes the synthetic data generator failure schema drift - generated column type mismatch, downstream load fails by applying the specific fix in the steps, proving it on one small scope first, then rerunning and reconciling counts. Use when this error blocks generation, validation or export. Not for platform outages, w…

Refresh the cached table schema instead of rewriting the query: Trino caches remote table metadata, so a column dropped at the source keeps failing until the cache is invalidated or the table is re-registered in the connector. Use when a Trino catalog over a remote or federated table whose schema changed at the source…
