Parsing issue with parsing service_documentation

[tanekim88]

In discovery.rs, I am seeing the following code, which does not allow service_documentation to be a non-empty and non_url at the same time:

https://618898.app.netsuite.com/.well-known/openid-configuration has a field "service_documenation" with a value of "TBD" (To be determined). It's not a full url, so it throws a parsing error when the following code is run.

let provider_metadata = CoreProviderMetadata::discover(
    &IssuerUrl::new("https://618898.app.netsuite.com".to_string())?,
    http_client,
)?;

=>

Error: Failed to parse server response
