I created a testing Zap that starts with a Javascript step, then calls an integration that I wrote.  The integration posts data to Azure.

The integration has a number of numeric inputs:

{
  key: 'CharterRate',
  label: 'Charter Rate',
  type: 'number',
  required: false,
  list: false,
  altersDynamicFields: false,
},

If the value being passed to the integration’s form is null, Zapier calls this “no data”:

Somehow, “no data” is converted to 211249053, which is posted to Azure:

Why is “no data” converted to 211249053?  Is there a way to prevent this?

** edit **

I’m handling this value in the integration’s perform method:

const perform = async (z, bundle) => {

  const options = {
    url: 'https://REDACTED',
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      Accept: 'application/json',
    },
    params: {},
    body: {
      DriverID: bundle.inputData.DriverID,
      CharterRate: bundle.inputData.CharterRate === 211249053.00 ? null : bundle.inputData.CharterRate,
    },
  };

  return z.request(options).then((response) => {

    const results = response.json;
    return results;

  });

};
