Referencing Field types in Value Table for JoinFeatures

DakotaMorgan — Mon, 06 Jun 2022 13:08:54 GMT

I'm trying to create a python script in ArcGIS Pro to perform a simple join on two feature layers. I am trying to add the Field objects to a Value Table as described in the ArcGIS Pro docs here https://pro.arcgis.com/en/pro-app/2.8/tool-reference/big-data-analytics/join-features.htm, but I'm not sure how to specify the relationship. I have created the Value Table, and I understand that the values are space delimited, I'm just not sure exactly what form the Fields should be referenced in.

I have a reference to the Field objects in the form of

<geoprocessing describe field object object at 0x000001C5AF296B50>

that I got using the ListFields() method. This is the address I get when using AddMessage(field0) to debug.

I am getting

ERROR 120034: At least one relationship is required.

when I call

arcpy.geoanalytics.JoinFeatures(targetFeatures, joinFeatures, outFS,"JOIN_ONE_TO_ONE", None,
None, None, None, attrRelations, None,
joinCondition, None, keepTargetFeatures)

I would greatly appreciate any help that can be provided!
