I have optimised the property in DEV… added the db instance in product and moved it to SIT.. I have checked the SIT Table as well, the optimised columns are present in db table… However during commit, I’m getting an “error unexposed property - column names”.

Hi @Yuvaraj after optimisation have u saved the db table instance? Just save table once and try.
