Sending HTML Data using Zapier API Request

Using Zapier to bring an email from my Gmail account into wrike as a Custom Item Type.

Zapier has a built-in "Create Task" option with Wrike, however, it only creates a "task" and there's no option to tell this action to create a custom item type instead, so I've instead strung together 3 API requests in Zapier.

1. POST command that creates the custom item type in a specific folder with the title being the subject of the email

2. PUT command to add a user to the created task

3. PUT command to pass through the email contents in HTML format to the description of the task

I’m having trouble with my third PUT command in Zapier. I'm using the string "description" and selecting "Body Html" to send the email body in HTML format, but nothing updates after running the command. Am I missing something? Alternatively, when I use the plain text version of the email body, it passes through to the task successfully, but all formatting is removed, which isn’t my intended solution.

I'll provide a screenshot below, forgive me as I'm relatively new to Wrike's API and still learning!
