SDK api post returns undefined when error

When using SDKs API, I make a post request. Tried async / await as well but no way can I get a handle error returned by request.

api
.post("users.create", {
name: data.name,
email: data.email,
password: data.password,
username: data.username,
roles: ["anonymous"]
})
.then(res => console.log(res))
.catch(error => console.error(error));

I get the following error on logs generated by API but no way can I get a handle on error thrown, all I get is undefined.

[API] POST error (users.create): {
success: false,
error: 'ajskajs is already in use :( [error-field-unavailable]',
errorType: 'error-field-unavailable'
}

Start by reproducing the SDK API POST for users.create with the shown promise and inspect how the request error is propagated to catch. Trace the POST error handling until the logged structured error is returned to the caller; done means the catch callback receives the error instead of undefined.
