Hi there,
I know that question has already been asked several times and answers where ticked as a solution.
But I failed to understand or apply the fix.
Here is my case:
I have created Discord Credentials for the appropriate channel Courses level2.
In the upper part of my workflow, notifying the team after have sent emailS works fine. I can see my messages in the Channel.
When I use the same credentials in the bottom part of my Workflow, in the Loop and after ‘Convert to file(csv)’ node, the Discord node doesn’t do the job.
Just changing the credentials weebook URL to a Discord channel of mine make the WF working perfectly 
.
Upper part of the workflow working with Courses webhook.
Bottom part of the worflow not working with Courses webhook (same as previous one).
Bottom part of the worflow working with my personal channel webhook.
Thank you,
Thomas.
