Unmarshal error when trying to list traces

[ibrahima]

I don't know if I'm using it wrong, but I get this error when I try to list traces:

scout --app my_app_id traces list --endpoint "endpoint_identifier"
Error: json: cannot unmarshal number 0.0 into Go struct field TraceEntry.traces.mem_delta of type int64

I used the Base64-encoded endpoint identifier that shows up in URLs. When I try to use the raw endpoint name I get a different error: Error: failed to parse response: invalid character 'N' looking for beginning of value so I assume the Base64-encoded version is correct.

Thanks!
