Webform to HubSpot Checkbox mapping does not work

Problem/Motivation

When mapping a Webform Checkbox (single checkbox) to a HubSpot Checkbox. The values don't match, resulting in a HubSpot error: "This value wasn't passed to the Contact record. '1' isn't one of the allowed options." for that mapped particular property.

Steps to reproduce

1. Create a Webform with a single checkbox, and another text input
2. Create a HubSpot with a single checkbox, and another text input
3. Adding the HubSpot handler and map the Webform to the HubSpot form, mapping the checkboxes together and the text input together
4. Try to submit the form
5. Check the submission on HubSpot. You'll notice that the text input value was sent, but the checkbox mapping displays an error: "This value wasn't passed to the Contact record. '1' isn't one of the allowed options."

Proposed resolution

• Change the value type for a single checkbox when mapped, from 1 to "true" and from 0 to "false"
