Spring Boot request header return null value

Question

I have a spring boot project which has some Rest APIs in it. I have two custom headers named request_date and tenant

Answer 1

Some network tools can drop headers that contain underscore in it's name. As per this answer underscore is a legal character but it's uncommon and sometimes tools require additional configuration to support it.

Rename your header to requestDate or request-date and see if it helps. If it works without underscore than inspect network route between client and server e.g. maybe there is a proxy that drops them?
