"Unable to convert row to 'DimensionFeature' "

Hallo everyone,

I copied and upgraded an ArcGIS Dimension Feature Class (File GDB) using ArcPy.
However, when trying to read it in FME 2024 (FeatureReader / File Geodatabase Reader), I get this error:

Unable to convert row to 'DimensionFeature'

FME can see the schema, but fails when reading the features.

Does FME support reading Dimension Feature Classes, or is there a known workaround?

Thanks.
