Else : a die broke all other action : https://github.com/LimeSurvey/LimeSurvey/blob/cd03fc7ed0d2840b4462994e5e4dc1a340b63796/application/core/LSYii_Application.php#L407
We need App()->end();

@gabrieljenik : can you give me the way to check the error ?
I mean

• Action to do
• Must show "this"
• show other.

Well, this poped up while reviewing the issue 18019
https://bugs.limesurvey.org/view.php?id=18019#c68937

Then we handled the exception and the LSJsonException is not shown there anymore.
Still the underlying problem exists.
Maybe you could go back to the previous coommit and review?

@gabrieljenik : you already have a solution for this one ? You want to fix it ?

Don't have a fix, but we were digging a bit when reviewing 18019
We can take it if you want.

If you're OK, yes please :)
I don't have idea here …
