I am recently getting an exception in my Kanbanoo UIX dashboard code in the M-Files classic desktop client when calling the ObjectPropertyOperations.GetVersionCommentHistory method on one specific M-Files object (which does have 4 version comments). It doesn't happen on every object, so far only on one object.
My logs show that the exception started occuring since June 18, 2025, the day I upgraded M-Files to 25.6.14925.4 (prior to that I was running 25.3.14681.8).
So it likely is a bug introduced between M-Files 25.4 and 25.6. (I didn't change my side of the code for a long time)
The bug is uncritical for me other than user won't get to see some comments, but I though you'd like to know about it.
The ObjVer that I am passing to the API call is:
{
"Type": 0,
"ID": 506,
"ObjID": {
"Type": 0,
"ID": 506,
"ExternalRepositoryName": "",
"ExternalRepositoryObjectID": ""
},
"Version": 41,
"ExternalRepositoryName": "",
"ExternalRepositoryObjectID": "",
"VersionEx": {
"Type": 4,
"Version": 41,
"ExternalRepositoryVersionID": "",
"ExternalRepositoryVersionSortKey": 0,
"ExternalRepositoryVersionSortKeyAsString": "0"
}
}
