Corrigo Error Code "ERRORCODE{Number}"

Hi Team,

I have an integration project client who has recently encountered a few errors like the following:

ERROR_CODE_1 (ActorId is a required field.)
ERROR_CODE_4200 (File 'sys_remote_update_set_36a0eee647437210486c2d8f016d4345.xml' is either unknown or not allowed)
ERROR_CODE_7 (Corrigo.BO.KnowledgeBase.InvPath BO not found)

As the Error Codes site (https://developer.corrigo.com/reference/http-error-code#http-error-code) did not really identify what are the possible [Number]s for the ERRORCODE and the definition of each Number, is there any other documentation/sites we can refer to in order to provide client information regarding the full picture
