I have a bit of SDK functionality that creates a featurelayer from a mapservice uri and then queries the layer for a search string using layer.Search(queryFilter) to retrieve a rowcursor, and then loops through the rowcursor to retrieve values using while (cursor.MoveNext())
This works most of the time but I occassionally get a geodatabase exception when calling MoveNext()
ArcGIS.Core.Data.GeodatabaseException: 'A geodatabase exception has occurred.'
COMException: Bad variable type. (Exception from HRESULT: 0x80020008 (DISP_E_BADVARTYPE))
Any ideas what could be causing this error? The same bit of code works perfectly for local layer files.
This isn't something we've seen before.
In theory, we know what is causing this; the error code tells us that the Variant's type isn't valid. In practice, we don't know what could be causing this.
If you have a consistent, or sometimes consistent, reproducible case, could you please log it with support?
