Are you able to access the admin panel? I've always just registered the first user through there

[grave trout]

I get redirected to the first user screen /admin/create-first-user where it fails to register the user - also happens on my local
On my local - I registered the first user on 1.6.16 which worked - will try to downgrade

[open zinc]

The latest version is 1.16.22, you could try using that? Why would you downgrade? Also maybe a stupid question but do you have your Payload config defined? And do you have the config path environment variable set up?

[haughty garden]

hmm what has a config property

just weird it happens on a collection config

[open zinc]

Mmm, yeah, we might need to see your config

Ok, I have found the issue. The plugin for last modified by from https://payloadcms.com/docs/plugins/overview was also adding it to the users - probably causing the validation to fail. So I created the first user way ahead and didn't go though that flow after while adding features/plugins. Thanks for helping !
