[SOLVED] No mapping for GET /v3/api-docs | not able to use swagger in spring boot app

I have created a spring-boot application, for blogging application. while I try to use swagger in spring-boot app to create a document for all the APIs I have created.

The GET http://localhost:8080/v3/api-docs is giving me a unauthorized error. even though I am using the correct token.

here is the classes I have created

I am not seeing any error logs for these, so it is a little confusing for me.

I tried to look for answers in stackOverFlows. I did get some questions, However I was not able to solve the issue I am facing

any help would be appreciated

thank you in advance
