Send Message Works with email, not with ID

Description/Error
I am receiving a 404 error when attempting to send messages to users using their ID. I am not receiving this error when using the user’s email. This is odd, as last week, ids as parameters worked perfectly. I have double checked that the id is correct, and have determined that the problem persists even when hitting the api endpoint from the zoom documentation site.

Which Endpoint/s?
https://api.zoom.us/v2/im/users/me/chat/messages

How To Reproduce (If applicable)
Steps to reproduce the behavior:

  1. Obtain a valid Zoom ID and email
  2. Attempt to send message with email as identifier for chat_user param, see message sends properly.
  3. Attempt to send message with the same user’s ID as the identifier for the chat_user param, receive 404 not found error.

Update
I did some additional testing and was able to find the recipient using their user ID and the “Get a specific User” endpoint: https://api.zoom.us/v2/users/{userId}
Still no luck sending a message to a User ID however.
