Florian Schmidt updated APEXCORE-776: ------------------------------------- Description: When launching an application, killing it immediately and trying to restart it with {{-originalAppId}}, the following stacktrace is shown. I *assume* that this is because the app never reached running state but was killed in submitted / accepted step. Expected behavior: Better error message as to why this error occurs. {code} apex> launch apex-test/malhar-examples-highlevelapi-3.8.0-SNAPSHOT.apa 1. AutoComplete 2. CombinePerKeyExamples 3.
