Server Shutdown - Unhandled Exception

[MaheshkumarSundaram]

Hi @ralphhanna,

Consider the following process,

Steps to reproduce:

• From bpmn-web's UI, I start the above process.
• Now, I delete the started instance before the timer event expires

• The timer event is completed by Cron I guess and the associated query throws error:

  Exception: stack Error: query produced no items for {"items.id":"1bd38074-627a-43b1-97ed-40ba479f620e"}
    at Logger.error (F:\myApp\node_modules\bpmn-server\src\common\Logger.ts:120:15)
    at Engine.<anonymous> (F:\myApp\node_modules\bpmn-server\src\server\Engine.ts:289:17)
    at Generator.next (<anonymous>)
    at fulfilled (F:\myApp\node_modules\bpmn-server\dist\server\Engine.js:5:58)
    at processTicksAndRejections (node:internal/process/task_queues:95:5)
  F:\myApp\node_modules\bpmn-server\src\common\Logger.ts:120
  }
  
  Error: Error: query produced no items for {"items.id":"1bd38074-627a-43b1-97ed-40ba479f620e"}
    at Logger.error (F:\myApp\node_modules\bpmn-server\src\common\Logger.ts:120:15)

    at new Promise (<anonymous>)
    at __awaiter (F:\myApp\node_modules\bpmn-server\dist\server\Engine.js:4:12)
    at Engine.exception (F:\myApp\node_modules\bpmn-server\dist\server\Engine.js:500:16)
    at Engine.<anonymous> (F:\myApp\node_modules\bpmn-server\src\server\Engine.ts:329:22)
    at Generator.next (<anonymous>)
    at fulfilled (F:\myApp\node_modules\bpmn-server\dist\server\Engine.js:5:58)

Result: The server abruptly terminates due to the above exception.

I believe this issue is a regression but not sure from which version though.

Could you kindly look into this? Thanks.
