Unable to update row in table 'Unknown column '_RowNumber' in '

[akbar]

I added a new column today to my AppSheet which is connected to a database table.  Lately  I am getting the error message when i am trying to sync the data captured. 

Unable to update row in table 'wbc_jpin_audit'. → Unknown column '_RowNumber' in 'where clause'

wbc_jpin_audit is the table i have connected. 

Why it could happen ? please help.
