I have a feature layer in AGO that is published every day with a related table. I have a script set up that creates new field indexes on the feature layer after it is republished. I noticed today that the field indexes weren't being created. When I run the script, I get the error "Exception: Unable to add feature service layer definition. A full-text index cannot be created on the table or indexed view because duplicate column 'FIELDNAME' is specified" I assumed this was a problem with the script, but when I go into AGO and try and manually create the field index it tells me that an index can't be created. I'm guessing this may have been happening since the last AGO update and I only just noticed. I'm fairly certain it is being caused by the related table as I don't have this issue with other layers that don't have related tables. Is this a bug within AGO or is this just a limitation I'm going to have to deal with going forward?
