Since Spring Boot 2.6.x we need to include server errors explicitly, stacktrace etc.
So, configure your application.properties
like this:
server.error.include-message=always
server.error.include-binding-errors=always
server.error.include-stacktrace=on_param
server.error.include-exception=false
Or configure your application.yml
like this:
server:
error:
include-message: always
include-binding-errors: always
include-stacktrace: on_param
include-exception: false
