Having issues deploying the app using now-sdk

[Logappradeep]

Hi Team,

We are facing an issue while deploying a scoped application using the ServiceNow SDK version 4.6.0.

Environment Details:

• SDK Version: @Servicenow/sdk 4.6.0
• Deployment Method: ServiceNow SDK CLI
• SDK Command Used:
  npx --yes @Servicenow/sdk deploy --debug
• Deployment Source Path:
  /workspace/build-copy
• Application Package:
  vpn_access_catalog_updates_0_0_1.zip

Issue Summary:
The application package is successfully created and uploaded, but the deployment fails during the installation status verification phase with the following error:

[now-sdk] DEBUG: Debug logging enabled
[now-sdk] Starting installation...
[now-sdk] DEBUG: packing directory dist/app to /workspace/target/vpn_access_catalog_updates_0_0_1.zip
[now-sdk] DEBUG: installing package /workspace/build-copy/target/vpn_access_catalog_updates_0_0_1.zip
[now-sdk] ERROR: Could not determine app installation status. Check instance to verify installation.
Error: Could not determine app installation status. Check instance to verify installation.
    at Orchestrator.install

Observed Behavior:

• ZIP package generation completes successfully.
• Upload process appears to complete successfully.
• Failure occurs only during installation status polling/verification.
• SDK is unable to determine the final installation state.

Troubleshooting Already Performed:

1. Re-ran deployment with --debug
2. Verified package generation
3. Checked credential cache behavior
4. Confirmed SDK authentication is successful
5. Attempted redeployment multiple times

Request for Support:
Could you please help investigate:

1. Whether the application installation is actually succeeding on the instance side
2. Why the SDK cannot retrieve or determine the installation status
3. Whether this issue is related to:
   • SDK polling/API issue
   • instance response timeout
   • app repository installation API behavior
   • platform version compatibility
   • known issue in SDK version 4.6.0

Please also confirm:

• Recommended SDK version for stable deployments
• Supported Node.js versions for SDK 4.6.0
• Any known fixes or workarounds for this issue

Kindly let us know if additional logs or instance diagnostics are required from our side.

Thanks in Advance!
