form 3.0.0 beta-.5 wrong action/redirect after submit

[axel-rank]

In my modular form.md I set
action: /
After submitting it redirected me to the start/header of my homepage. I implemented a modal success box which shows the success message.
This was working in form 2.16.4
In form 3.0.0-beta.5 after formsubmit it redirects to /home/_contact which does not exist and results in an error 404, page does not exist message. I tried different routes for action parameter, but it seems action setting not working anymore.

Action should be fixed now.

Yes, working again!

Made some extra fixes to allow modular forms to work without action: / in them. In that case, the form will be submitted using the current URL.
