ORDS_METADATA.ords_export.export_module ORA-20850

Hi All

Kindly, I was trying to export my ORDS web service DML, but I got the following error, I search in oracle community and I found it's bug and only it will work if I execute the command from SQLcl, but unfortunately, it does not work and returned the same error, please help

DB: 11.2.0.4

SQLcl: 19.4.0.3

ORDS: 19.2.0.r1991647

SQL> SELECT ORDS_METADATA.ords_export.export_module(p_module_name=>'MYORDS') FROM dual;


Error starting at line : 1 in command -
SELECT ORDS_METADATA.ords_export.export_module(p_module_name=>'MYORDS') FROM dual
Error report -
