Spring Authorization Server Metadata Endpoint not compatible

[jsantana3c]

Describe the bug

• Spring Authorization Server 1.3.0 metadata endpoint not compatible, it generates a "Null" Path, which prevents the serialization of jackson, preventing the creation of the openapi json.

To Reproduce
Steps to reproduce the behavior:

• What version of spring-boot you are using? 3.3.0
• What modules and versions of springdoc-openapi are you using? webmvc-ui-starter
• What is the actual and the expected result using OpenAPI Description (yml or json)? json
• Provide with a sample code (HelloController) or Test that reproduces the problem -> just add spring authorization server with defaults

Expected behavior

• spring authorization server metadata endpoint default url
  Screenshots
  the matcher is a lambda, so that's probably the reason why the code doesn't work properly
  

so in the method
org.springdoc.core.configuration.SpringDocSecurityOAuth2Customizer#buildPath

no matching is being done, and the path ends up being null.

Additional context
spring is checking if it has multipleIssuers, so maybe you can guys customize the code and check if isMultipleIssuersAllowed directly and apply the default DEFAULT_OAUTH2_AUTHORIZATION_SERVER_METADATA_ENDPOINT_URI, otherwise leave it with the /** by default?

you just exclude @SpringBootApplication(exclude = {SpringDataWebAutoConfiguration.class}) and it will be fine

I'm having the same issue and this didn't fix the problem. From testing locally it looks like upgrading spring-security-oauth2-authorization-server to version 1.3.0 from 1.2.4 is when the issue started, so some change in the most recent version of that dependency started the issue.

If I had to guess it was this change that's causing the issue: spring-projects/spring-authorization-server@4cfe59c

If I had to guess it was this change that's causing the issue: spring-projects/spring-authorization-server@4cfe59c如果我不得不猜测是这个变化导致了这个问题：spring-projects/spring-authorization-server@ 4cfe59c

you can see this issues spring-projects/spring-data-commons#2937

@jsantana3c,

The check if isMultipleIssuersAllowed can be done only in spring-security context on the runtime of the http request.
I have added a fix so both endpoints are exposed by default.

Hey @bnasslahsen, is there a workaround before the fix released? I really can't downgrade authorization server to 1.2.4.
And it would be great if you provide the time schedule that we can get the fix in a release. Thanks!

@bnasslahsen I just tried the release candidate, and seems that it's still not working.

@joaquinjsb,

Not working, will not really help :)

Feel free to provide a Minimal, Reproducible Example - with HelloController that reproduces the problem.

sure, i'lll create another issue, but seems that the exception is still the same:
com.fasterxml.jackson.databind.JsonMappingException: Null key for a Map not allowed in JSON (use a converting NullKeySerializer?) (through reference chain: io.swagger.v3.oas.models.OpenAPI["paths"]->io.swagger.v3.oas.models.Paths["null"])
