Additional information

Inizia in commands/deploy_command.go, da getMtaArchive alla riga 543, quindi segui executeInternal alla riga 239. Riproduci il problema con Cloud MTA Build Tool 1.2.33 e cf deploy mta_archives/xxx.mta usando le versioni elencate. Il lavoro è terminato quando il comando non va più in panic durante il deployment di un archivio MTA.
