Hi Appwrite team,
I'm getting a consistent deployment failure on Appwrite Cloud. The build itself completes successfully, but a post-build sidecar step then fails.
What the logs show:
- npm install runs fine ("added 2 packages … found 0 vulnerabilities")
- Packaging completes the log prints "Auto compression: squashfs", the squashfs filesystem is created at /mnt/code/code.sqfs, and "[open-runtimes] Build finished" is logged
- ~5 seconds later the deployment fails with:
[sidecar:build] Build archive was not created at /mnt/code/code.tar.gz
So the runtime produces code.sqfs, but the sidecar appears to be looking for code.tar.gz and doesn't find it.
Why this looks like a platform-side issue, not my code:
- It reproduces from a second, independent machine.
- It also fails when I redeploy an OLDER deployment that previously built and ran fine — with zero code changes.
Environment / details:
- Runtime: Node 18+
- Entrypoint: src/main.js | Build command: npm install
- Project ID: [FILL IN]
- Function ID: [FILL IN]
- Region: [FILL IN]
- Failed build timestamp: 2026-07-08, ~18:40 UTC
Several other users report the same "Build archive was not created at /mnt/code/code.tar.gz" error in the community threads, so this may be a known platform regression. Could you confirm whether there's an ongoing incident, and share a fix or workaround? I'm happy to provide the full build logs and the deployment ID.
Thanks,

Summary
Deployment failed at the sidecar step due to "Build archive was not created at /mnt/code/code.tar.gz" in Node 18. An applied fix should resolve the issue – try again and confirm if the problem is resolved.
