Model Studio

Internal server error.

Error details: org.springframework.transaction.UnexpectedRollbackException - 'Transaction silently rolled back because it has been marked as rollback-only'

If you inspect the data-mining log from the time of the issue, the following error is displayed:

ERROR: value too long for type character varying(40)

This combination of errors in the user interface and the data-mining log occurs when the user name for the user who creates the project is longer than 40 characters.
