Power BI Refresh Error:
Partial Parse Error
What does this error mean?
Dbt encountered an inconsistency between the cached parse state (manifest.json or partial_parse.msgpack) and the current project files. This surfaces after package upgrades, model renames, or changes to schema.yml files.
Common causes
- 1A dbt package was upgraded and its macro signatures changed, invalidating the cached parse tree
- 2A model file was renamed or moved and the old cache entry still references the old path
- 3A schema.yml definition was changed in a way that conflicts with a previously compiled manifest
- 4The partial_parse.msgpack file was generated by a different dbt version than the currently installed version
- 5Multiple dbt processes wrote to the target/ directory concurrently, corrupting the cache
How to fix it
- 1Delete the target/ directory and re-run: `rm -rf target/ && dbt run` — this forces a full re-parse.
- 2In dbt Cloud, trigger the job with the `--no-partial-parse` flag to bypass the cache for one run.
- 3If the error appeared after a package upgrade, run `dbt deps` to reinstall packages and then clear target/.
- 4Check that only one dbt process is writing to the target/ directory at a time — parallel jobs sharing a target/ directory will corrupt each other's cache.
- 5Pin the dbt-core version in your requirements.txt or pyproject.toml to prevent silent version drift between local and Cloud environments.
