I get the following error while setting up Firebase as an AWS IAM Identity Provider using OpenID Connect.
We encountered the following errors while processing your request: Please check .well-known/openid-configuration of provider: https://securetoken.google.com/
<Project ID> is valid.
The AWS IAM Identity Provider setup requires two input parameters, to which I plugged in the following:
Provider URL: https://securetoken.google.com/<Firebase Project ID>
Audience: <Firebase Client ID>
To troubleshoot the error, I opened http://<Provider URL>/.well-known/openid-configuration in a browser and noted the JSON response has the Issuer and jwks_uri fields. I believe these JSON fields indicate the Firebase OpenID Connect Provider URL is valid.
Any idea how I could avoid the above error and successfully set up the AWS IAM Identity Provider?
