Power BI Refresh Error:
DbtPartialParsingError

What does this error mean?

dbt's partial parsing cache is stale or corrupted, causing it to fail when trying to incrementally parse the project.

Common causes

  • 1A major refactor (renaming packages, changing dbt version) left the partial parse cache inconsistent
  • 2The partial_parse.msgpack file in the target/ directory is from a different dbt version
  • 3A dependency was updated and the cached parse state references nodes that no longer exist
  • 4A git merge conflict resolved incorrectly left the project in a state that partial parsing cannot handle

How to fix it

  1. 1Step 1: Delete the partial parse cache: rm target/partial_parse.msgpack.
  2. 2Step 2: Run dbt parse or dbt compile for a full re-parse — this rebuilds the cache from scratch.
  3. 3Step 3: If the error recurs after a full parse, check for genuine YAML syntax errors with dbt parse.
  4. 4Step 4: Add target/ to .gitignore to prevent stale cache files from being committed.
  5. 5Step 5: Set --no-partial-parse flag in dbt Cloud job settings to disable partial parsing in CI.

Frequently asked questions

What is dbt partial parsing and why does it exist?

Partial parsing allows dbt to skip re-parsing unchanged files, significantly speeding up parse time on large projects. It stores the parse state in target/partial_parse.msgpack between runs.

Can I disable partial parsing permanently?

Yes — add --no-partial-parse to your dbt command or set partial_parse: false in dbt_project.yml. This increases parse time but eliminates cache-related issues.
