I didn't adjust the tests, which is why the pipeline complains.

But I was testing manually and it doesn't work.

Hmm, what's the status with this?

[tessus]

This PR implements the limit as was shown at stackoverflow. You can build the app and test it. But it doesn't work. Same behavior as before, except that now you don't even get an error message after the file has been uploaded. Apparently limiting the fie upload is just not possible with this framework or every single information out there about how one can accomplish this is wrong.

You pinged the author here #336 (comment) but nothing so far.

[orhun]

I see. I might come back to this later then.

Yea, this one is a draft and was just to show that it doesn't work as described in the stackoverflow article.
We can leave it for reference for now. Who knows maybe Rob will check it out... ;-)
