Error: Argument 'client_id' is required but was not present

[ayezinzu]

I have my app running on Github codespaces and I set the app url from there as my redirect uri in the data client. It gives me this error. Am I doing something wrong?

For context, I want to integrate an hybrid app via oauth2.0

In regards to the same, I have one more question being, where I can I access a reference ( i.e client id ) to the user installing this app, when they redirect to my custom app for authorization?
