Error staging application: App staging failed in the buildpack compile phase problem

Hello, We are developing a Mendix app to push MindSphere OS. We have finished to develop first simple app but while trying to push the app via cloud foundry, we get an error as it is in the capture. We are not trying to push the app through a manifest file, which we tried and failed, but we are trying to write all the disk_quota, memory, instances, buildpack, health_check_timeout instances through cloudfoundry commands. Does anyone has an idea about this error? Thank you for your help beforehand.
