Viz Plugin Issue: 405 Method Not Allowed

[badman-rodriguez]

• I followed the format given in the Blog Article: https://preset.io/blog/2020-07-02-hello-world/

But instead i get an error when trying to run a query:

Essentially it is erroring out here:

else {
    url = '/api/v1/chart/data';
    console.log(formData, force, resultFormat, resultType, '')
    payload = buildV1ChartDataPayload({
      formData,
      force,
      resultFormat,
      resultType,
    });
  }
  postForm(url, payload);

INFO:werkzeug:127.0.0.1 - - [31/Aug/2020 11:13:39] "POST /api/v1/chart/data HTTP/1.1" 405 - Server log
When running any other Viz plugin, query runs fine with no issues. Its specifically when following this documentation.

Superset Version: 0.37
Node: 12.14

Any insight would be very helpful! thanks!
