Sudden increase in Queue callback error: BadRequestError: {"error":"Visibility timeout exceeds message expiration"}

This morning we started noticing the following errors spike significantly.

INFO] [vercel.workflows] Starting winback workflow {
workflowId: 'HIDDEN',
stayId: 'HIDDEN',
userId: 'HIDDEN'
}
[INFO] [vercel.workflows] step_delay { stepNumber: 1, stepCount: 2, duration: '1d', sleepMs: 86400000 }

We have been running workflows in production for 4 weeks now without issue - where is this coming from? It is breaking running workflows.

Start by tracing the reported stack path through QueueClient.changeVisibility and ConsumerGroup in the bundled index.js, using the Visibility timeout exceeds message expiration error as the entry point. Determine why production workflows now hit this queue callback failure and verify that running workflows no longer break.
