Deployment test: TypeScriptAzureContainerAppJobDeploymentTests hangs waiting for success prompt

[mitchdenny]

Test

Aspire.Deployment.EndToEnd.Tests.TypeScriptAzureContainerAppJobDeploymentTests

Symptom

Hex1b automation times out after 5 minutes waiting for the success prompt:

Xunit.MicrosoftTestingPlatform.XunitException: Hex1b.Automation.Hex1bAutomationException : Step 31 of 31 failed — WaitUntil("success prompt [9 OK] $ (fail-fast on error)")
  WaitUntil timed out after 00:05:00 waiting for: success prompt [9 OK] $ (fail-fast on error)

Total test runtime: 5m 43s before the timeout fires.

Root cause analysis

The TypeScript AppHost flow (apphost.ts) appears to hang or fail silently during one of the long-running CLI commands (likely aspire publish or aspire deploy) without producing an error prompt. Needs deeper investigation by walking the recorded terminal capture.

Reproduction

• Scheduled Deployment Tests runs on main: consistently failing on the last 5 nightly runs.
• Also reproduced on PR Fix WithIngressClass parameter resolution for Kubernetes publish #17423 deployment-test run #26348648275 (unrelated to PR change — PR only touched src/Aspire.Hosting.Kubernetes).

Sibling failures pointing at TS apphost infra:

• Deployment test: TypeScriptJavaScriptHostingDeploymentTests fails early with ERR exit code (sequence 10) #17437 — TypeScriptJavaScriptHostingDeploymentTests
• Deployment test: AksAzureKubernetesEnvironmentCertManagerTypeScriptDeploymentTests cannot find apphost.ts #17438 — AksAzureKubernetesEnvironmentCertManagerTypeScriptDeploymentTests

Priority

High — blocks TS Azure Container App Job E2E coverage every nightly run.
