ERROR: Bad id_token issuer https://www.linkedin.com/oauth&error=invalid_request when using cognito and using LinkedIn as OIDC provider

Question

Hey guys getting this error instead of an access token in the URL header when going to `https://YourDomainPrefix.auth.region.amazoncognito.com/oauth2/authorize?response_type=code&client_id=YourClientId&redirect_uri=redirectUrl` (with correct details filled in)  and logging in to LinkedIn successfully:
```
ERROR: Bad id_token issuer https://www.linkedin.com/oauth&error=invalid_request
```
 with Cognito using OAuth2 via LinkedIn (the OIDC provider). This randomly (i.e. nothing new was deployed) started happening on the 16th of April and I think it may actually have something to do with Cognito and not my app but I could be wrong?

Accepted Answer

You might need to update your Issuer URL from **https://www.linkedin.com** to **https://www.linkedin.com/oauth** in the AWS cognito user pool settings where you configured the LinkedIn as an Identity provider.
