How do I use a parameter to call a feature class in a Feature Reader when I run a workbench from a python script?

thanks @MarkAtSafe !

that worked for me when I read a feature class from a file geodatabase.

However when I try to do read a feature class from a SDE geodatabase, I get an error which starts with 'Too many recursive macro substitions -- line currently is: `SOURCE_READER GEODATABASE_SDE CONNECTION_FILE "$(CONNECTION_FILE)"

Do you know what may be causing this error?

@surbhi It looks like you've created a parameter and are using that parameter to set the SDE connection file parameter that already exists. I might try disabling your existing Geodb SDE reader in the navigator and then adding a new Geodb SDE reader from scratch and see if that fixes your workspace

Hi @surbhi, you can try to use a ParameterFetcher to fetch the connection file and pass that parameter as an attribute instead of as a publish parameter in the FeatureReader.
