Migrating Report Package between environments

Content

Hi, 

I'm trying to export and download a report package and after I'm trying to import this artifact (zip file) in another environment using Library (like this: https://docs.oracle.com/en/cloud/saas/enterprise-performance-reporting-cloud/urpsn/migrating_artifacts_from_one_environment_to_another_environment_173500.html)

I always did this way but this time is not working. 
Before when I uploaded the zip file of my Report Package, and automatically the NR recognized like a Report Package, but this time the NR is not recognizing the zip file like a Report Package.

may someone help me?

Thanks, 

​Tales
