Scala Play Framework: Header doesn't exists - scala

Question

I am trying to run play application and it runs correctly. However, while serving to few APIs, I get following error:
[error] play - Cannot invoke the action, eventually got an error: java.lang.RuntimeException: Header doesn't exist
[error] application -
! #714mk098l - Internal server error, for (POST) [/ivi/customer/login/] ->

I feel like this should related to configuration rather than code issue. Can someone please guide here?
