Why are the headers not being read/sent?

Question

PHP

I am correcting the mistakes of another programmer, but the problem turned out to be this:
the php yii2 framework is installed on the server.
The code is there:
$request->getHeaders()->get('Authorization');
The application sends the header:
Authorization: bearer $token$
using okhttp
the problem is that when I output $request->getHeaders();
then among all the headers there is no Authorization.
I use ChuckInterceptor to view requests in a mobile application.
What could be the problem?
ps my authentication fails due to the missing Authorization header, but if I look at the ChuckInterceptor debugger, it says that the header has been sent.

Answer 1

the problem was the following, CPanel was installed on the server, and Cpanel was removing the Authorization header for its own security.
There were 2 decisions to do something with Cpanel (this is a separate order from a freelancer).
and change the authorization header, for example, to tokenApi and parse something from it.
