500 error when inviting to identity

I have just set the signup to invite only, when I try to send an invite this is what I get.

I recently have upgraded my account and now I am not able to use the service. Please can someone have a look or update this ticket if you have questions.

We’ve followed up on this request in our helpdesk, feel free to continue conversation there.

I would rather update this ticket here please.

Is there a problem with my identity service? I recently updated it to a Level 1 and I think since doing this the service and /signup endpoint is not working.

With black Friday around the corner we will incur a big financial loss if the signup service is returning a 500 error.

Please can someone send an update here why I am no longer able to send an invite to a user using identity.

All of a sudden the service is not working.

You wrote an email to me stating the following:

Netlify Identity is being formally deprecated, so although it remains possible to use the service, we are no longer able to support it. Identity remains a feature of Netlify - it won’t be taken away from existing websites.

I have an existing website which is no longer able to use identity.

Please can someone get back to me to update me as to why the following endpoint for identity works

.app/.netlify/identity/user

Yes the one for signup which is causing us a problem returns a 500 and doesn’t work.

.app/.netlify/identity/signup

Unfortunately, I’m not able to provide any additional information here that wasn’t already provided in the helpdesk ticket.
