Vectle found the following relevant skills: - agent failed to complete dbt test run error timeout on large model - Compilation Error: model 'stg_orders' depends on a node named 'raw_orders' which was not found"
Problem outcome: unknown
Public search query: dbt build failed error "compilation error: test depends on missing model ref"
Problem outcome: unknown
Before applying any schema-drift fix, build the downstream impact list first: find every model, dashboard, and check that reads the changed column, then fix drift by adding compatibility, such as a renamed column kept alongside the old one, instead of renaming in place. Use when an agent repairing schema drift in a pi…
Read the manifest diff before rebuilding: a schema change detected error means the built model's columns no longer match what the manifest or contract recorded, so compare the model SQL's output columns with the recorded schema, then either restore the dropped or renamed column or update the contract and downstream re…
Vectle found the following relevant skills: - agent loop detected: agent retrying failed dbt test in infinite loop error - agent loop detected: re-running failed dbt tests with no changes
Problem outcome: unknown
Public search query: dbt run error: test failed in manifest with schema change detected error
Problem outcome: unknown
Vectle found the following relevant skills: - agent hallucinating label classes not in ontology caused QA failure error - agent hallucinating department names that do not exist: generated wrong values and validation failed with error
Problem outcome: unknown
Public search query: agent hallucinating dbt test names in schema yml caused compilation failure error
Problem outcome: unknown
Validate the file or payload header and schema version first, read the input in named chunks with a summary per chunk, and keep the tail records instead of truncating at a fixed character count. Use when this exact failure blocks a named record, run, or build in dbt Semantic Layer. Not for a different error message or…

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…
Query the source grouped by the key to find the duplicated keys, fix the upstream join or dedupe rule that produced the second row, and only then re-run the refresh. Use when you see this exact failure in Power BI and the affected record or object can be named. Not for a different Power BI error with another message, …
Staging is where source nulls first become visible, so query the raw source for the nulls before editing the model: if the source sends nulls, either filter or coalesce them in staging with a documented rule, or move the not_null test to the model where the field is truly required. Use when a dbt staging model failing…
Look the object up by listing the current workspace rather than trusting the stored id or name, remap the reference to the current id, and fail loudly when a listing has no match. Use when you see this exact failure in Tableau and the affected record or object can be named. Not for a different Tableau error with anoth…

Fixes a dbt accepted_values test failing on the churn_status column so cancelled accounts stop being coded as active, by tracing the unexpected values to their source model. Use when the test lists values outside the allowed set. Not for relaxing the test to hide real data problems.
Fixes a Looker PDT build that fails because the table already exists, leaving a dashboard empty, by clearing the stale derived table and rebuilding. Use when the PDT regenerator errors and dependent tiles show no data. Not for a PDT that builds but returns wrong rows.
Fixes a Snowflake SQL compilation error saying object USAGE_EVENTS does not exist so the churn scoring job runs again, by correcting name resolution and access. Use when the job fails at compile time. Not for a query that runs but returns wrong numbers.
Fixes the dbt compilation error where a model references a node dbt cannot see, by checking the ref name against real model files, defining missing sources, and re-running dbt compile. Use when dbt compile or dbt run fails with a 'depends on a node' error. Not for warehouse errors that happen after compilation succeed…
Fixes a snapshot broken after an agent reordered models in the DAG, moving the snapshot before an upstream model it depends on. Use when a snapshot runs against stale or missing upstream data after a DAG change. Not for snapshots whose upstream is a raw source.
Fixes a missed downstream ref after an agent renamed a model file, leaving a stale ref that fails compilation. Use when a rename was done by file operation without updating callers. Not for intentional model removals with planned downstream changes.
