After investigating the logs from the traces table in Application Insights, I noticed that the function ExcelOutCheckDoc was not executed. I also confirmed that under normal operation, there would be a log entry showing "executing ...." and Spring boot started, but this time, no such log appeared.

My environment information

  • Function App plan: Y1
  • Operating System: Windows
  • Runtime version: 4.1037.0.23521
  • Java 17
  • Spring boot

Can someone help me identify the root cause?
Thank for all your helps.
