Hello,

I'm getting an incomprehensible error when I try to add a dependency between a trigger prototype and a trigger in the same template: "Undefined array key".

I don't understand because if I add the dependency to a different trigger or if I clone the template and add the dependency as intended, I don't get this error.

I've tried renaming the template and recreating the items/triggers, but nothing works.

(Even though cloning the template works, I can't use that method because I would lose too much history on my servers.)

My Zabbix is version 7.0.21.

 

Steps to reproduce:

1. Click on the trigger prototype.
2. Click on "Dependencies".
3. Click on "Add".
4. Select the trigger.
5. Click on Update --> the error message appears at that point.

 

Result:

Expected:

It works if the template is cloned:

 

Best regards,
