Package Inspection Error APNX-1-4268-003

Hi,

I'm trying to import an application from instance A to instance B.

Export was successful on all objects, but import inspection results to "The uploaded file is invalid (APNX-1-4268-003)".

When I try to import it to instance C, inspection does not throw any error.

Instance B already contains a previous version of the application while instance C doesn't, so I tried deleting all objects and the application in instance B,

but it still results to the same error.

I can't seem to find the logs in jboss1-stdOut.log as well.

Anyone familiar with this error or where I could find the inspection logs?

Thank you!
