Liquibase Update/Rollback for Function does not work

Trying to update an existing SQL function, the SQL code is correct (have run it directly on the database) but cannot get Liquibase to run it successfully, or roll it back :frowning:

Liquibase says ‘Migration Successful’ on update but nothing is changed in the DB, and ‘Migration Failed: Unknown Reason’ on rollback.
