ZIP deployment fails with HTTP 424 "Runtime initialization time exceeded"

[naumaanh]

When using deployment_type: zip in config.yaml, the AgentCore Runtime fails to start and returns:
HTTP 424: {"message":"Runtime initialization time exceeded. Please make sure that initialization completes in 30s."}
After checking CloudWatch logs for the AgentCore Runtime, you can see multiple ModuleNotFoundError crashes at startup:

ModuleNotFoundError: No module named 'tools.gateway'
followed by:
ModuleNotFoundError: No module named 'agentcore_tools'

Steps to replicate:

1. Set deployment_type: zip in infra-cdk/config.yaml
2. Run cdk bootstrap & cdk deploy
3. Deploy frontend
4. Open the web app and send any message
5. Observe HTTP 424 in the UI and ModuleNotFoundError in CloudWatch as well as the error in the frontend
