in that specific case it seems to be a problem of the plugin. Will issue a PR there.

But the same occurs when trying to export a goal specific report. Not yet sure how to solve that.

I had a quick look...

diff --git a/core/Plugin/Report.php b/core/Plugin/Report.php

+        if ($this->hasGoalMetrics) {
+            $goals = Request::processRequest('Goals.getGoals');
+            foreach ($goals as $goal) {

+            }
+        }
     }

Something like this would be kind of needed that makes the report metadata for all those reports available. Problem is that the "report metadata" would get pretty pretty big and they would be even shown in the mobile app etc which we might not want to... (unless we really do)

Not sure how to fix it otherwise either. It is definitely tricky.

@tsteur could you maybe open this in a PR so we can see the failing tests and how much data this would be?

It's not a solution. That's why I didn't even create the PR

It's also happening with Users Flow when clicking eg on "interaction 1" and then on export
