I am using typescript SDK (REST API V2) for importing Groups using GroupsApi.importUserGroups and saved id and name of groups created from API response. Then later tried to use that group_id to share models using SecurityApi.shareMetadata but says principal does not exist. Then I ran /api/rest/2.0/groups/search API call for that org, the ID in the search group response does not match with ID we got as part of importUserGroups response. I used group name as identifier for now but interested to know why IDs are not matching?
