Can't invite users to new account - "Issue validating invite token"

[paim_clickbus]

Describe the problem/error/question

I just created a Pro account on n8n, and now I’m trying to add new users, but the invite links sent to email are not working. When I open the link I’m directed to the login page, with a notification in the corner saying “Issue validating invite token. Invalid request” (image below).

At first I thought it was a problem only with my work email, because I’ve already used n8n before (but it’s workspace has already been deleted). But then I sent invites to co-workers who never used n8n and they had the same issue.
I’ve already tried updating to the lates stable n8n version (1.95.3), restarting the workspace, re-sending the emails, deleting the users and sending the invites again, and the problem remains

Searching the forum I only found this related issue, but I verified my invite links and the id’s are not being sent duplicated, so it’s not the same problem

What is the error message (if any)?

“Issue validating invite token. Invalid request”

Hello!
Sorry about that, here some checks and tests that come up in my mind:

• Try opening the invite link in Incognito Mode or another browser
  This ensures no conflicting session or cookie is interfering.

Also, try opening on desktop if the invite is being opened on mobile.

• Check the full URL of the invite link

It should look something like this:
https://app.n8n.cloud/workspace/[workspace-name]/signup?token=abc123…

If it’s redirecting to just the login page without preserving the ?token=…, the link handling is broken.

• Manually add the token to the URL
  If you know the token (e.g. from the invite email), append it manually:

https://app.n8n.cloud/signup?token=abc123

• Revoke the current invites and issue fresh ones
  Even though you’ve tried this, do it again after restarting the workspace

Hi, thanks for the quick answer!

I’ve tried incognito mode, and I’m only using desktop to open the links.

But I think the problem is in the invite link, because the links in the emails don’t have the token parameter.
They are following this format (clicked right mouse button on email and copied the link):
https://<workspace>.app.n8n.cloud/signup?inviterId=<uuid>&inviteeId=<uuid>. Then after milisseconds I’m redirected to:
https://<workspace>.app.n8n.cloud/signin

Any guesses on what could cause the token to not be sent on the invite links?

Found out the problem was having an empty account First Name (it was blank). I’m not sure how this happened because it’s a mandatory field, but after filling it the invite links started working.
