How to integrate with Discord Webhook

Dear Support:

How to make the webhook action of Uncanny Automator to send messages to Discord Webhook?

I have posted the webhook URL to Uncanny Automator and hit the test button, but to find errors below.

Server has responded with error code: 400 https://discord.com/api/webhooks/1293757624130736158/8AU3WNPdUd78DFUnhIPm5idV6eZA3p-S340o2zsM_EkmWmW1QM_frolVQK5CmUXCGtK_
