I am trying to set an index on string field and it fails with following error:
Column 'COUNTY' in table 'db_45156.user_45156.SWITRS_20190830_PRO_SWITRS_20190830' is of a type that is invalid for use as a key column in an index.
(Error Code: 400)
I have been using the same column for indexing years without an issue. Is this no longer supported?
