Can't generate changelog from sap ase15.7 database

I am new here and begin to use liquibase to migrate my database from sap ase 15.7 to postgres, however i am getting the above error when trying to genrate changelog.
command: liquibase generate-changelog --log-level=debug --changelog-file=dbchangelog_1.sybase.xml
Error:
ERROR: Exception Primary Class: UnexpectedLiquibaseException
ERROR: Exception Primary Reason: Unknown boolean value: N
ERROR: Exception Primary Source: 4.27.0

Thanks in advance for your help !

Hi @seven4,

Would you mind sharing your liquibase.properties content so we have a better picture on how your setup looks like?

Thanks,
Daniel.

hey @seven4,

Do you have your any boolean column defined as a char ā€˜Nā€™? If the answer is a yes, then the reason of your error could be the below block of code for Sybase:

 else if ((database instanceof SybaseASADatabase) || (database instanceof SybaseDatabase)) {
            return new DatabaseDataType("BIT");
