Geoprocessing Service - Field Parameter Not Supported

[LanceKirby2]

I see in the ArcGIS Pro documentation here: Input and output parameters for geoprocessing services—ArcGIS Pro | Documentation that the field parameter should be supported. I am running ArcGIS Pro 2.5 and ArcGIS Enterprise 1.7 so I should meet all requirements; however, after publishing the GP service I receive the message below when setting up the service within the Geoprocessing widget. Any ideas?

Can you show your tool parameters before publishing?

[LanceKirby2]

Sure.

In my script I am using GetParameterAsText

    featureLayer = arcpy.GetParameterAsText(0)

    fieldName = arcpy.GetParameterAsText(1) 

    outPutName = arcpy.GetParameterAsText(2) 

[DavidPike]

Hmmm, perhaps set the first 2 parameters as arcpy.GetParameter(0) and  (1).

I'd take a stab at the dependency not being set as no object is input, however this is just a hypothesis.
