Current behavior

This code:

ExAws.S3.put_object(Application.get_env(:ex_aws, :bucket_name), filename, binary)
|> ExAws.request

returns me:

[error] #PID<0.1313.0> running Vae.Endpoint terminated

The actual parameters of the put_object call are fine.

Expected behavior

I checked for the

Please re-send this request to the specified temporary endpoint. Continue to use the original request endpoint for future requests.

and it seems related to region-specific issue along with bucket creation so it may go away by itself.

That said, shouldn't the lib handle the case so that the issue goes up to application code instead of triggering a no case clause matching error at lib level.
