The error is indicating that the application bits, i.e. the SCS broker worker, are not detected by the Java buildpack as a valid Java app (i.e. the Java buildpack doesn't know how to run the app). Since this app is coming from the SCS tile & it's being pushed by the SCS errand & we test this extensively, this shouldn't generally happen. The app bits should always be good and should get pushed in a consistent way.
The only thing that stands at as different at this point is that it's referencing an online buildpack. We don't normally see that because the SCS tile will default to use the Java buildpack that ships with the platform. Please go into Ops Manager -> SCS Tile -> Settings -> SCS and change the Buildpack option to `java_buildpack_offline`. This should use the default buildpack, not one from the Internet. Save & apply changes. Let me know if the problem persists.
Thanks
