Damn! I got it!
While i was generating this post, i found the error causing code-part.
It was not the → ELSE ← statement, it was the → .catch() ← what caused the error.
But this is strange isn’t it? I do return anything in my → .catch()-part.
Deactivating the .catch()-part → resolves the issue.
A simple → [ ] ← is assingable as data to repeater.
Or another way to solve it…
.catch((err)=>{console.log(err); return [];});
But that’s kind of confusing. For me not logical.
Anyway → Deserves —>Best-Answer<— THANKS for TIP!
