Can't make Gmail.User.start_mail() work

[silvagustin]

Hi! I'm trying to use this dependency and after setting everything up and running:
{:ok, pid} = Gmail.User.start_mail(user_email, user_refresh_token)

I got the following error:
** (MatchError) no match of right hand side value: {:error, {:function_clause, [{Gmail.OAuth2, :do_refresh_access_token, [%{}, "1//04ml-27by0C3PCgYIARAAGAQSNwF-L9Irco4pMbDE1fJWAG38b-LpVPd-sfm9V9Fr6-3Xk-0Ecp883KXO40eANwViDYqCW3klUWU"], [file: 'lib/gmail/oauth2.ex', line: 53]}, {Gmail.OAuth2, :refresh_access_token, 1, [file: 'lib/gmail/oauth2.ex', line: 34]}, {Gmail.User, :init, 1, [file: 'lib/gmail/user.ex', line: 20]}, {:gen_server, :init_it, 2, [file: 'gen_server.erl', line: 417]}, {:gen_server, :init_it, 6, [file: 'gen_server.erl', line: 385]}, {:proc_lib, :init_p_do_apply, 3, [file: 'proc_lib.erl', line: 226]}]}}

Is this still working?

Cheers.

I had this same issue, and I realized it was because I had not added the client id and client secret to my config file. Look at the dev.exs.sample config file in the repo for an example of what it should look like. That solved it for me!
