I'm using some of the API calls of Rocket.Chat to send and update status reports from our CRM. For one of this reports, it is necessary to update existing messages in Rocket.Chat and this is currently not working.

I'm trying to send the following request:

POST /api/v1/chat.update HTTP/1.1
X-Auth-Token: fw7KEtEU_XEcn-L1s568Xnqi_XT_bzCmOtWiwKzVwUx
X-User-Id: 5wh5EXP79hDg3L4WP

Content-Type: application/json; charset=utf-8

Content-Length: 75

{"roomId":"K2EbA7Kg63CfngGfT","msgId":"GTmmkvqXsweHWXamm","text":"foo bar"}

And I get the following answer:

HTTP/1.1 400 Bad Request

{
  "success": false,
  "error": "Cannot read property 'description' of undefined"
}

Maybe a message with a attachment is causing this? Since only messages with attachments have the description property

Ok. This is a message without an attachment - so this might be the problem here.

edit:

I guess, I'm producing this trouble by myself. The message, I'm going to update is posted with the chat.postMessage call. I don't want Rocket.Chat to create an attachment to this message by its own (there is a link included) and therefore I'm sending an empty list in the attachmen variable. This causes the error described above.

This results in another question: How can I prevent Rocket.Chat from creating an automated attachment?

{ parseUrls: false }

@gerricom add the above code to your message

Thanks, @graywolf336!

This should still be considered a bug since there is an error occurring.
