Hello everyone,
I am writing because, when I try to open the condition designer in a survey (in the website version), the following error appears. In other surveys it does not appear and I can use the condition designer properly. Please, I would like to receive some help. Thank you.500: Error interno del servidorarray_merge(): Argument #2 must be of type array, null givenOcurrió un error interno cuando el servidor web procesaba su solicitud.Por favor contacte a Administrator para reportar este problema.

You didn't answer the basic questions at the beginning of each new post on the forum:

So what version of LS are we talking about? And where is it hosted? On your own server? By LImesurvey GmbH?

As I understand, this only happens with a specific survey and is not a general problem? What does the integrity check say? So what happens if you copy the survey in question?

There must be something in the survey that causes this error.

In general I recommend not to use the condition designer but rather write your own conditions via Experession Manager/Script, it still needs to work as long as it is a feature of Limesurvey. As outdated the approach via condition designer might be.

Debug is set ?

PHP8.X ?
