Hi I keep getting a cryptic email but I don't know why or how to investiage it? I haven't made any recent changes but it started about two weeks ago. See email below:

Subject: Developer script exception from (Company) : SlackOpportunityPublisher for job ID 7074M00005mBr87. : Argument 1 cannot be null

Message: Apex script unhandled exception by user/organization: 00561000001ZL2O/00D610000007iZw
Failed to process Queueable job for class SlackOpportunityPublisher for job ID 7074M00005mBr87.
caused by: System.NullPointerException: Argument 1 cannot be null
Class.SlackOpportunityPublisher.QueueableSlackCall.execute: line 36, column 1

If anyone can make sense of this or has any recommendations I would appreciate it.
Thanks -Mark

I think you need to check the code which will require some development skills. I think something is wrong with the webhook url. 
Check SlackOpportunityPublisher class to see if any argument passed to the method is null.
