Improve message of lacking fields

[janvlug]

I filled in all mandatory fields as far as I can see, but still I cannot Generate the publiccode.yml.

I get this message:

But I cannot figure out which form field is invalid.

hi @janvlug. As stated by the message, it seems a validation error message.
Is there any form field with a validation error message?
It'd be displayed below the form field.

I filled in all mandatory fields. There are no fields with an error message of something red.

This issue is about the fact that I do not know which field is not validating. I'm using the LibreWolf browser.

I've never ever tested this app on LibreWolf.
LibreWolf can run a wasm? Validation is executed on wasm
