run-aci - randomly fails to end test

Version info:

Artillery: 2.0.30
Node.js:   v24.7.0
OS:        darwin

Running this command (in Azure Cloud)

artillery run-aci  artillery.script.ts

I expect the tests to complete within 20/25 minutes but sometimes they get stuck until the actual Azure ADO pipeline times out.

In the logs, I see this error message being repeated over and over

this comment I got from my colleague from dev ops team

Artillery's ACI mode spills large queue messages to blob storage (overflow/). At phase end the straggler worker either failed to upload its final summary blob or it got cleaned up before the orchestrator fetched it. The orchestrator then retries forever instead of giving up — almost certainly an Artillery bug in aci.js:290 / aqs-queue-consumer.js:58 where a missing blob is treated as retryable with no budget.

Thanks in advance
