@opensearch-project/admin could you please re-direct to notifications dashboards.

I'm also having this issue, I think there needs to be more control of the way the parameters are sent

I figured it out. The test message looks like this:
Test message content body for config id <id>
But that is not valid JSON. Discord expects a value for the "content" key. In the Create Monitor page, you can put in the full message. If you format it as JSON it works.


There needs to be a way to put a custom test message in the hook setup
