http_request_opts = [
  ssl: [
    verify: :verify_peer,
    cacerts: :public_key.cacerts_get(),
    customize_hostname_check: [
      match_fun: :public_key.pkix_verify_hostname_match_fun(:https)
    ]
  ]
]

For some odd reason whenever I pass this opts (this is for test environment), it threw an error:

     ** (ArgumentError) cannot convert the given list to a string.

     To be converted to a string, a list must either be empty or only
     contain the following elements:

       * strings
       * integers representing Unicode code points
       * a list containing one of these three elements

     Please check the given list or call inspect/1 to get the list representation, got:
    .....

So this http_request_opts, which is a list, is converted to string? If I’m not passing that opts (just empty list) it ran just fine.
