After Upgrade to Talend 8, NullPointerException

Papademuchos — Fri, 15 Nov 2024 21:57:14 GMT

I just upgraded to Talend Studio 8. When I open a job and run, I get a null pointer exception (see screenshot below). When I click on Code, it comes up blank.

I've also updated to JDK 11.0.17.

I've updated my system environment variable to the new JDK folder;
I've updated the "Installed JREs" to the new jdk folder under Preferences -> Java
I also updated the POMS via Project Settings -> Build -> Maven -> Default -> Project

Any ideas?

Hello @Torry Slaton ,

Regarding to the error log, seems the studio workspace is corrupted, could you please restart the studio using a new workspace to re-try?

Attached is the log file.

I renamed my old workspace and opened up in a new one and that helped with many of the jobs issues. However, I'm still having this issue of NullPointException on a couple of jobs. The log attached here shows my issue from this morning trying to open / run one of the jobs giving this error.

A few things from the log:

org.talend.commons.exception.CommonExceptionHandler - Studio can't access the resource from server, please check the resource url.

Does this mean it's being blocked by the machine running Talend?

Thanks for your help.

I figured out my problem with the NPE. These jobs were using Data Mapper to convert to/from EDI. For some reason, after upgrading to Talend Studio 8 all of my HL7 and X12 projects with their structures, etc. went missing. After adding them back in using the Feature Manager the jobs worked again. The NPE was because the job was referencing some of these structures and they weren't there.

To make it clear, a NullPointerException actually means, the developer writing this code is a leazy developer and does not care about the users of the code!
