Change in $sp.getCatalogItem functionSummaryOne of the notable changes in $sp.getCatalogItem function in Service Portal between Kingston and London release is in the _field object which is returned. On Kingston or previous releases _field object contained multiple object in format IO:<sys_id> On London or later releases _field object contains multiple objects in format <variable_name> To summarize: in London or later releases we return the variable's internal name instead of the sys_id with IO: prefix. If you have been using _fields in your customization, please review and change your code according to the changes mentioned above
