Generating Credentials Auth Error - redirect_uri

I'm receiving an Authorization error when attempting to generate an authorization code:

Error 400: invalid_request

You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy for keeping apps secure.

If you’re the app developer, make sure that these request details comply with Google policies. redirect_uri: urn:ietf:wg:oauth:2.0:oob

I've used this Google tutorial to replicate and confirm the issue:

https://developers.google.com/assistant/sdk/guides/service/python/embed/install-sample?hl=en_US

It is generating this URL:

https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=[HIDDEN]&redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fassistant-sdk-prototype&state=[HIDDEN]&prompt=consent&access_type=offline

Here is a workaround provided by jdtoth on Github: https://github.com/greghesp/assistant-relay/issues/266#issuecomment-1065940698

Thanks jdtoth!

I found a workaround for creating a new user. In my case, I needed to create a specific type of API credential. Here is what I did:

Create a new OAuth Client credential using the link below, ensuring the application type is "Web application" and set Authorized Redirect URIs to "http://localhost"

https://console.cloud.google.com/apis/credentials

Download the key, and create the user in the Assistant Relay appas you tried before. When it opens a new browser window to authorize the google account, you might need to bypass a warning. After you do this, a blank browser window will open but the address bar will contain the auth code you need. Grab the code from the relevant part of the URL here and paste it back into the Assistant Relay app:

http://localhost/?code=COPYCODEFROMHERE&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fassistant-sdk-prototype

Let me know if this works. I am successfully sending commands to the Assistant Relay server but nothing is playing on my speakers.
