UI Authorize button - OAuth2 with clientCredentials returns error of CORS

[weesftw]

After configuring the securitySchemes and filling in all the elements (flows, tokens, scopes), the button to authenticate returns the CORS error and the OAuth server side is ok... it seems to me that swagger-ui does not send headers valid CORS, how can I configure this?

• spring-boot version 2.6.6
• Using springdoc-openapi-ui version 1.6.8

example swagger.yaml.

@weesftw,

CORS is related to your configuration.
You need to have CORS enabled, on your applications that is blocking the swagger-ui.

@bnasslahsen,

The question is: do I need to configure CORS on the part of my application that is swagger-ui or oauth server?

@weesftw,

You should allow CORS requests.
The answer depends on each application architecture...
