Error catalogueSign-in at the EHR
Redirect URI rejected at sign-in
What it means
The EHR says the redirect_uri is not registered for this app. It must match a registered value character for character: scheme, host (localhost vs 127.0.0.1), port, path and trailing slash all count.
Fix
Copy the registered redirect URI from the vendor portal and use exactly that string (--redirect-uri).
