Authentication failure - invalid_client: No such API key: Bearer

[micha1805]

Every time I try to connect to the Stripe Connect API I get this failure in authentication, 'redirecting' me to the failure method of the Omniauth callback controller :

E, [2018-05-28T13:41:50.435158 #58778] ERROR -- omniauth: (stripe_connect) Authentication failure! invalid_credentials: OAuth2::Error, invalid_client: No such API key: Bearer
{
  "error": "invalid_client",
  "error_description": "No such API key: Bearer"
}

I found in the doc that an error of invalid_client meant either one of these :
https://stripe.com/docs/connect/oauth-reference#post-deauthorize-error-codes

• client_id does not belong to you
• stripe_user_id does not exist or is not connect to your application
• API key mode (live or test mode) does not match the client_id mode

But i doubled checked and it's none of these.

Does anyone has an idea ?

Did you fix this on your own, or move this to a different project?

For others who may find this, when I was facing this issue, it was because I did not properly set up the omniauth initializer to include the required stripe keys:

I had set up this file:

# config/initializers/omniauth.rb
Rails.application.config.middleware.use OmniAuth::Builder do
  provider :stripe_connect, ENV['STRIPE_CONNECT_CLIENT_ID'], ENV['STRIPE_CLIENT_SECRET']
end

But forgot to put the keys into my .env file.
