Error on calling get

[rmartinezalbano]

Im trying to get users or pay method and I have this error:

[VERBOSE-2:ui_dart_state.cc(148)] Unhandled Exception: NoSuchMethodError: The getter 'keys' was called on null.
Receiver: null
Tried calling: keys

If a try by the URL by web i receive the information.

The caller is:

mp.get("/v1/payment_methods", authenticate: true, params: {});

Thanks!
