I'm getting an error using a script that previously worked for updating a layer. The error is a string name that is too long for something identified only as 'identifier.' (I'm not sure why this is an error from the truncate function, which should be deleting rows.) I'm replacing the string with X's, but somehow it's ending up as two repeats of the name of the feature layer, so it is over 128 characters.
I can't figure out which 'identifier' this is. I printed out target_layer.properties and found that the string was the name of one of the spatial indexes, so I rebuilt the spatial indexes for the layer. Now the identifier no longer shows up in those indexes. But the error from the script has not changed, it still thinks there is an 'identifier' with this too-long string. There is nothing else under target_layer.properties that has the too-long string as its name.
What else could I do to find where/how this happening?
Here's the error:
