We have analyzed this issue and found that the MySQL user configured with ganib doesn't have access to required METADATA.
To resolve this issue you need to execute below GRANT queries with MySQL admin user.
GRANT SELECT ON mysql.proc TO 'ganibuser'@'%';
GRANT ALTER ROUTINE, CREATE ROUTINE, EXECUTE, SHOW VIEW, CREATE, DROP ON ganib.* TO 'ganib'@'%';
Once those queries are executed successfully restart the ganib instance and check registration process again.
Please let us know if you need any other help.
