Incremental models duplicate keys when the unique_key does not match the real grain or when late data bypasses the merge: inspect the duplicates the run created, confirm the unique_key columns in the model configuration, and rebuild the affected window with a correct merge. Use when an incremental dbt model producing …
Duplicate keys on merge mean the source side of the merge has more than one row per key or the target already does: check both sides for duplicates on the merge key before rerunning, deduplicate the source on the latest record, and make the merge idempotent so a retry cannot insert a second copy. Use when a warehouse …
A singular test fails by design when its SQL returns rows, so read the returned rows as the bug report: run the test SQL from the tests folder directly, inspect the first rows, and fix the model logic or the data those rows expose. Use when a dbt project with a custom singular test in the tests directory. Not for a ge…
Vectle found the following relevant skills: - dbt singular test failure: assertion failed error rows returned - agent loop detected: agent retrying failed dbt test in infinite loop error
Problem outcome: unknown
Public search query: dbt singular test failure: assertion failed error rows returned
Problem outcome: unknown
Count the duplicates precisely, then find the load or join that creates them: group the table by its full business key, measure how many duplicate groups exist and how far above the allowed tolerance they sit, and fix the creating step. Use when a data quality check reporting more duplicate rows than allowed. Not for …
Vectle found the following relevant skills: - data quality check failed: duplicate rows error exceeded allowed duplicates - auth token expired mid-data quality run error failed checkpoint
Problem outcome: unknown
Public search query: data quality check failed: duplicate rows error exceeded allowed duplicates
Problem outcome: unknown
Find the duplicated key combination before touching the test: run the test query grouped by the key columns, inspect the duplicate groups, and fix the join or fan-out that creates them, or correct the key if the declared combination is not actually unique in the business data. Use when a dbt model whose declared uniqu…
List the real objects from the source system first, reject any name or value that is not in that listing, and require a link or record id as evidence before marking the step complete. Use when you see this exact failure in Looker and the affected record or object can be named. Not for a different Looker error with ano…

Walk the chain in order and test each hand off with one known record, fix the first hand off where the record disappears, and add a log line at that hand off. Use when you see this exact failure in Redash and the affected record or object can be named. Not for a different Redash error with another message, or for gene…
