Migration from Postgres to MySQL using MySQL Workbench (Error in Reverse Engineering catalog. A task has failed while execution)

When I am trying to migrate database from Postgres to Mysql, I am facing an error in the Reverse engineering source step in which the log shows

Same error can be seen when i migrate the complete Postgres database or only a single schema. So what would be the reason for it?
