The Analysis

It seems something is missing or incorrect in the Jaspersoft ETL installation or configuration that causes this kind of error. Further investigate found Cmdline startup is giving the error message below when trying to do initRemote to the Local TAC:

!ENTRY org.talend.commandline 1 0 2020-10-07 15:16:19.677

Upon verifying the Jaspersoft ETL license, it turns out that the user is using Jaspersoft ETL license on Jaspersoft ETL BigData Extended version product.

The Suggestion

Please download and deploy the "regular" Jaspersoft ETL 7.3.1 product and have it installed to use it with the user's current Jaspersoft ETL 7.3.1 license to create the new jobs.
