Please, help 
Following instructions in the Course 2 Workflow 2:
-
Use the Discord node to send a message in the n8n Discord channel
#course-level-two. In the node, configure the following parameters:-
Webhook URL: The Discord URL you received in the email when you signed up for this course.
-
Text: "I sent the file using email with the label ID
{label ID}. My ID: " followed by the unique ID emailed to you when you registered for this course.
Note that you need to replace the text in curly braces{}with expressions that reference the data from the nodes.
-
But when try to execute, get an error.

I checked credentials, spaces in the message - all seems to be correct.
Also tried to send the same message to Telegram - it worked with no errors.
