If you are trying to automate Vertex AI Agent deployments using GitHub Actions or Cloud Build, you likely ran into issues with serialized Python objects.
The new Inline Source Deployment feature solves this by allowing you to package code directly. This method allows your CI pipeline to deploy fresh code without needing a persistent GCS bucket or risking binary incompatibility between your build runner and the Vertex runtime.
You can find code and blog here to get started!
Happy building!
