OIDC login error

Facing below error for OIDC setup with google cloud.
Parsing error for OIDC discovery document: [Line 1, column 0: Unexpected end of stream.

Appreciate your help.Thanks!

Can you check if the format matches one of the ones listed at OpenID Connect & OAuth 2.0 API | Okta Developer ?

The get call for the https:// ${yourOktaDomain} /.well-known/openid-configuration returns 200 OK
