Slack & Discord URL Missing Required Parameter 'user'

So I’ve been having trouble figuring out what was causing my scenario’s be deactivated. I found that when people posted links or hyperlinks on Slack the trigger would happen and the message would be sent to Discord but if another message is sent by the user or another use the scenario would deactivated due to an error stating validation failed for 1 parameter(s). Missing value of required parameter ‘user’. I’m not really understanding why or what is causing this.

This is what happens when I send a new message. The scenario crashes. Here is the Output for Slack new Event:
