Request headers not being filtered. Httpc

[Ivor]

I am using Tesla, with Httpc and ExVCR in my project. I sign requests with basic authentication. I am trying to setup the VCR recording to filter out the basic authentication.

I wanted to test that my config is working so I could remove it by using a hardcoded authentication value and filter_sensitive_data. That works, but when I use a regular expression to match it fails.

This is my config in test.exs:

config :exvcr, [
  filter_request_headers: ["Authorization", "authorization"]
]

As you can see in the response below this doesn't work. I am testing how my code handles the remote server being down so the failed_connect should not be unrelated. The fact that I can remove, for example, the context-type using filter-sensitive-data tells me its not related to the entire ExVCR setup but to specifically filter_request_headers.

      "headers": [],
      "status_code": null,

    }
  }
]

Hope someone can shed some light. Thanks!

🙈 hmm, now its working. I must have changed something. I'll try and figure out what happened.
