Hello,

Did you make any migration? If so, could you please confirm if you are importing job from the lower version to the higher version or vice versa?

This might be caused by a job saved. Could you please see if you can reproduce this from a job newly created in your current studio V 7.3.1 (not an old job)?

Best regards

Sabrina

Hi,

This is not a migration. I created a new job and saved it then closed it. When I try to reopen the job I get the error below:

An error has occurred. See error log for more details.

JsonIoException setting field 'status' on target: OK null with value: {name=null}

Hello,

Does this issue repro on all your jobs or a specific one? If the former, there might be installation issue with your studio.

If the latter, could you please post your job design screenshots here? Which will be helpful for us to address your issue.

Best regards

Hi @Nolan Jones​  did you find a solution ?

I have the same problem but on the latest version 8.0.1, I didn't make any migration and I've this exact same error message while opening a job.

I specify that I work on a project that I did not develop myself.

But the thing is : this job was opening really well last week and nothing has changed in the meantime.

I'm completely stuck right now 👾

Thank you by advance

Hello @Charlotte To​ 

Here is a reply from your another topic

Please take a look at it?

https://community.talend.com/s/question/0D55b00008PzDnzCAF/talend-open-studio-801-error-opening-a-jo...

Note: JDK 17 isn't a supported Java environment, maybe you have upgraded your Java version recently, please install Java 11 and restart studio.

Best regards

Sabrina

Hello @Xiaodi Shi​  yes this another topic is mine, I posted because I need help

Hello,

Does the solution of installing JDK 11 work well for your talend open studio 8.0.1?

Best regards

Sabrina

Hello, yes absolutely the problem came from the JDK configuration.

We can close this ticket.

Thank you for your help !
