This error type is reported when a failure happens in the DNAnexus Execution Environment. Normally, this is not the application's fault, but the error may also occur because the application improperly specified its package dependencies in the runSpec.execDepends field of its app metadata.
Failed while installing execDepends
This error may happen when the runSpec.execDepends field of your dxapp.json application metadata file contains an invalid package name. Workaround: Check your dxapp.json for correctness of the execDepends field.
