Okta Authenitcation fails for Python Flask app .004 version

Here is part of my client,secrets.json file:(excluidng client_id and client_secret

"auth_uri": "dev-30359346.okta.com/oauth2/default/v1/authorize",
"token_uri": "https://dev-30359346.okta.com/oauth2/default/v1/token",
"issuer": "https://dev-30359346.okta.com/oauth2/default",
"userinfo_uri": "https://dev-30359346.okta.com/oauth2/default/userinfo",
"redirect_uris": [
  "https://sjcbiobox.driscolls.com:9460/oidc/callback"
]

this is the redirect URL (both for login and logout) for the application in my developers account

https://sjcbiobox.driscolls.com:9460/oidc/callback

I’m not sure how the URL is formed as I’m trying to recover an application left by an employee who has left - I used the same approach for the app that works fine with Okta.

Any suggestions what I might do to get around this problem - I’m a backend algorithm engineer who had been sidled with these problems.

Thank you Cale for any help you can provide.

Does this have any relationship to the Initiate login URI : https://localhost:5000 or are we just concerned w2ith the redirect login?
