Emby (500 error) notifications issue - Slack

[sesipod 0]

I am getting an 500 error when trying to setup Slack Webhooks in Emby. 

 

Log: at the bottom of this post under images
I have tried a new webhook url and still the same issue.

 

 

 

 

 

 

 

Here is the log for the webhook send: I have deleted the webhook form my slack before posting for my security.

Hi, slack sent an error response saying it was a bad request. I think you might be misunderstanding this feature - it's not built for slack specifically. Whatever is receiving the webhook requests from emby server needs to know how to understand them.
