@ruthvd​  If you can include a small sample of the dataset and your workspace that might help track down the cause of the issue. You might have a reserved word in your schema

Thanks for the suggestion Mark!

In the meantime I did some more tests. It turns out that the issue is not related to the schema but to the File Geodatabase.

Writing to a File Geodatabase created with ArcCatalog (pre-ArcGIS Pro) works.

Writing to a File Geodatabase created with FME works.

Writing to a File Geodatabase created with ArcGIS Pro generates the error.

The hypothesis now is that the open API feature writer is not compatible with File Geodatabases created in ArcGIS Pro. Is that possible?

@ruthvd​ Yes - it is probably dependent on the version of FME you are using whether the ArcPro File Geodb is compatible with the FME File Geodb File API writer

It makes sense that older FME versions are not compatible with newer ArcGIS Pro versions.

In this case however, I created the filegeodatabase in ArcGIS Pro 2.8.8 and the FME version is 2022.1

The cool thing about the Esri Geodatabase (File Geodb Open API) Reader/Writer is, that it is based on the File Geodatabase API. So, No additional software is required to use this format , but less functionality is available than with some other Esri Geodatabase formats. You say that the File Geodatabase you are writing to has been created with ArcGIS Pro. So, I guess that somewhere under the hood this fgdb is using functionality not supported by the open API...

But hey, If you have ArcGIS Pro running on your FME machine you might just use the Esri Geodatabase (File Geodb) Writer instead.

HTH,

@ruthvd​ It is an issue with the API used for the FME File Geodb API format. At this point it is not compatible with File Geodatabses that have been created using ArcGIS Pro 3.x

@Mark Stoakes​ That's what the compatibility table says. But this case indicates the writer also not to be compatible with lower ArcGIS versions , like version 2.8.8
