Forms link shows error when not logged in and shared with users

[uli-heller]

Describe the bug

I created a form, added some users to the form, copied the link to the form into an email which I sent to the users,
The form is not anonymous. When the users click on the link, they typically see something like this:

It reads "form not found".

However, if they log into nextcloud before clicking on the link, everything works ok.

To Reproduce
Steps to reproduce the behavior:

1. Create a form which is not anonymous
2. Invite some users by sending them the link to the form
3. Ask them to activate the link without being logged in within nextcloud
4. See error

Expected behavior

After clicking on the link, the user should be redirected to the login page and after logging in the form should show up.

Hey!
I will need a screenshot of your network requests.
Before you do anything, still on the development tools, there is a tab called network. Click on it and then the xhr filter. Open the form and screenshot the network log like this:

Click on the request and select the "response" tab, copy and paste the entire response content here please.

[uli-heller]

@skjnldsv : The list of requests/responses is empty when XHR is activated.

[skjnldsv]

I mean from the admin side, not the public :)

[uli-heller]

Sorry, I do not understand what you want me to do... Logging into Nextcloud and jumping into the edit mode of the form? And collecting network responses during this procedure? This will not reproduce the error...

[skjnldsv]

Logging into Nextcloud and jumping into the edit mode of the form? And collecting network responses during this procedure? This will not reproduce the error...

Yes, please do that.
I don't want to reproduce the error, but to get the form data :)
