Description: Invalid value for 'client_id' parameter

Hello, I’m new to okta and trying to get up and running. I’ve got a test rails app I’m migrating from devise to okta authentication and am almost there but I get
‘Description: Invalid value for ‘client_id’ parameter.’ when I’m redirected to where I should login.

The following is the full url, and the client_id param was retrieved from the application I created here:

Are you sure the client ID matches when you configured in your OIDC app? If so, I’d recommend sending an email to so they can look at your org and see what’s happening.

I’m about as sure as I can be, in console
ENV['OKTA_CLIENT_ID'] == <id pasted from clipboard> returns true

I’ve reached out to the email you provided, appreciate it!
