please make sure your package size is less than 256MB.

Update: We have now tried multiple additional fixes including:

• Excluding .next/cache from build to reduce package size below 256MB
• Adding ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION: true to force Node 20 in GitHub Actions runner
• Restoring original package versions

None of these have resolved the issue. The failure continues at exactly 32-33 seconds during polling on every deployment attempt.

Also noting that issue #1761 appears to be the same problem affecting .NET 8.0 apps, suggesting this may be a platform-wide Azure Functions deployment issue on the backend.

Can Azure team please investigate the backend logs for our deployment ID?
