Getting Invalid UUID message when trying to create new account

[manumitted]

Describe the bug

I am just starting to use LibreSign. I'm trying t-mail signatures. If I don't use the create account option, it wants me to upload a file. Probaby a certificate file? Our external people we want to sign probabaly don't have that. So, I'm trying the one where you create an account. But it's failing because it says it doesn't know the UUID. This is both NC32 and NC33. Create account You need to create an account with the same email address you received the invitation from. Invalid UUID

To reproduce

Start a signature on a file. Use an e-mail person. Locate the signature. Ask for signature. Got get e-mail. Enter in another browser that isn't logged in as me. Paste in link from the "Sign " part of the e-mail. Fill in the fields for creating a new account. See it say the UUID is bad. The below is copied from the page.

Create account

You need to create an account with the same email address you received the invitation from.

Invalid UUID

Expected behavior

I would expect to have a new account made. Would it be a guest account? Do I need the guest app? I don't even know exactly what to expect.

Screenshots

Create account

You need to create an account with the same email address you received the invitation from.

Invalid UUID

Environment information

Linux mint, older version. Seems like prerequisites are installed. Installations tested both NC32 and NC33 latest versions with latest app version.

Additional context

I'm not sure even exactly what to expect. I'm trying this out for a non-profit that I volunteer for, and I maintain a Nextcloud instance for it. We discussed using Docusign, but I thought I'd try this one. I've been working with shareware and open source software for decades, and like to promote it, especially in cases like this. The flow with a current user (not an e-mail user ... at least when I assign myself) seems to work fine.
