To Reproduce:

Request.new(:GET, "/accounts", "", key, secret, Request.server_time) |> Request.send!
** (ArgumentError) you must merge onto an absolute URI
    (elixir) lib/uri.ex:518: URI.merge/2
    (httpotion) lib/httpotion.ex:455: HTTPotion.normalize_location/2
    (httpotion) lib/httpotion.ex:455: HTTPotion.request/3

Notes:

This error is being caused (I suspect) because HTTPotion's normalize_location/2 function calls URI.merge/2 without the prepending http[s]:// to the URI. This causes the authority key in the URI struct to end up nil, meaning that URI.merge/2 is the function being called.

Since this hasn't happened for the other Coinbase calls (see Request.server_time/0), I suspect that when HTTPotion follows a redirect, the resulting string that URI is expected to parse is formed in a way that HTTPotion/URI doesn't expect.

Task:

Verify that this behavior is caused by the redirect, implement a workaround, and consider submitting an issue/PR to HTTPotion.

It may be possible to resolve this by using a different HTTP client in the Tesla configuration.
