Getting this error with

asset_reconciliation_sensor

, however all my assets are partitioned...

dagster._core.errors.DagsterInvalidInvocationError: Parent partition key provided, but parent asset is not partitioned.

hi @Daniel Gafni! Sorry you're running into this. I'm digging into the issue, and having a bit of trouble replicating -- some questions: Do you have multiple code locations / cross-code location dependencies? Are you consuming from source assets at any point? Did you just start trying out the sensor, or was it working for you before and this error is new? Also happy to talk more about the specifics of your setup (via DM or otherwise)!

The answer to all of your questions is “yes” (I’m trying the sensor for the first time)
