Test 2 - build with azure preset test with curl

yarn build:azure (or if you are on windows yarn build:azure:win

Followed by yarn swa:build - This runs the build with @azure/static-web-apps-cli (swa - azure static web apps service emulator) and azure-functions-core-tools (serverless framework)

Curl takes 10 seconds to complete, and it is missing all of the events except the last line.

Able to reproduce this issue after deployment to Azure Static Web Apps
