There is an issue with downloading and uploading an IFC component

[jingyangking]

After downloading and uploading an ifc component in ifc format, uploading it to bimserver cannot be opened using bimserver, and this ifc file cannot be converted to format using ifcconvert

The component I downloaded from bimserver cannot be converted by ifcconvert, and when opened in Revit, it also shows "cannot be opened". It is unclear what is causing this issue
