I have an API in which I'm getting api_key from headers. This is what I'm doing,

request.httprequest.headers['api_key']  , It works fine on my local but when I'm doing  the same thing on odoo sh then it won't get api_key from headers. I debugged and found that there's no api_key present in headers. Why it is happening? Im using Odoo sh version 16.

I have found that this guy is facing the same error:
