Asset Advisor OEM Failed to import

The error messages is like the image above:
SCO_Common-Extension:8.0.0 Import Failed: java.lang.NullPointerException
AppHomePage-Extension:8.0.0 Import Failed: java.lang.NullPointerException
I need some help here. What could possibly be wrong here ? Did Someone face the same issue before?
Thank you,
Vinícius Xavier.
