Error form login authentication

If you access the page after modifying from basic authentication to form authentication, you will receive 500 errors
om.ptc.mvc.controllers.ExceptionController  - message : Handler dispatch failed; nested exception is wt.method.AuthenticationException
error:-------------org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is wt.method.AuthenticationException org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is wt.method.AuthenticationException

The same log as comes out.

You can log in on OOTB, but it's an error that comes out when you access the developed page.

How should we resolve the above errors?
