Should i just copy this code block
method OnErroredResponse(pErroredResponseStatus As %Status, request As %Library.Persistent, ByRef response As %Library.Persistent, pCompletionKey As %String) as %Status
 

or should I rename it, also how to invoke this method. I could not find any sample code

@Eduard Lebedyuk 
Could you please show me how to code the MakeTimerCall in the custom code in BP. I am having similar issue. Any help is appreciated.
