I am trying to do something as shown below.

input_icrm

is generating the pandas dataframe to be used as input for the asset

ph2_calculation

. when running dagit, I get the following error:

dagster._core.errors.DagsterInvalidDefinitionError: Input asset '["input_icrm"]' for asset '["ph2_calculation"]' is not produced by any of the provided asset ops and is not one of the provided sources

At some place I have to convert the input/upstream asset to SourceAsset?

are you sure both are included in the same repo? This dependency should definitely be getting tracked.
