When outputting ESRI Enterprise records on FLOW 2026.2.1 via FeatureWriter with Dynamic settings and supplying ‘native_data_type’ attribute{} payload and ‘fme_format_short_name’ attribute (supplied from a FeatureReader schema port that connects the original data table) the workbench run generates masses of warnings around data-type mismatches whereby the fme_data_type is being attempted and not aligning with the target data-type:

Following details from Dynamic Workflows: Destination Schema is Derived from a Schema Feature – FME Support Center on initial testing results in the above messages. I have attempted to remove the fme_data_type and force recognition of the native, without success. What is missing for the engine to honour the ‘native_data_type’ directive?

The fme_format_short_name is “SAFE.ESRI-AGOL.ARCGISFEATURESERVICE”
The ‘native_data_type’ payload for each attribute is correct from the source table - it is the self-same table being updated at the end of the process:
featurereader/schema + data → attribute{}.native_data_type + fme_format_short_name → FeatureWriter “schema from schema feature”



Any help greatly appreciated.
Cheers
