Error trying to compile application in Delphi 10.3 Type mismatch for field

[joceravolo 0]

I have a working application that I want to bring to 10.3.

Type mismatch for field 'field', expecting: BCD actual: FMTBcd.

Any idea how to proceed?
I already deleted the field and added it again, deleted and did not added it back just to test, same problem.

This is happening with a lot of queries. So the application does not work.

I had a similar error with a type mismatch with a date field in MSSQL, due to a new data type being introduced that wasn't recognised by the driver. Found the new driver and all was well.
