You have a new Talend install that is using PostgreSQL for TAC DB config. You notice the following error when performing a check on the version:
500 The call failed on the server; see server log for details
The error is because of a permission issue of the user on the PostgreSQL DB. This is verified by manually logging in to Postgres and executing the command to create a test table.
Grant the user, in this scenario the user talenduser, access to the DB schema so they are able to create tables.
