aws lambda start with context

[laurenleach]

use context with aws lambda start options for ctx logger

Summary by CodeRabbit

• Refactor
  • Improved consistency by ensuring enhanced logging and telemetry context is used throughout the Lambda server command lifecycle.

Walkthrough

The context object used in several function calls within the Lambda server command implementation was updated from the original context to a newly initialized, enriched context (runCtx). The Lambda start invocation now explicitly passes this context, ensuring consistent propagation of logging and telemetry throughout the command lifecycle.

Changes

Cohort / File(s)	Change Summary
Lambda Server Context Usage pkg/cli/lambda_server__added.go	Updated various function calls to use runCtx instead of ctx; changed Lambda start to use StartWithOptions with context.

Poem

In the server's warren, context hops anew,
With runCtx in its paws, it knows just what to do.
Telemetry and logs now follow every trail,
Through Lambda's winding tunnels, context will not fail.

Learning: The connectorbuilder.NewConnector function in the baton-sdk already validates the connector parameter and returns appropriate errors for nil or invalid connectors, so additional nil checks are not needed before calling this function.

Learning: The connectorbuilder.NewConnector function in the baton-sdk already validates the connector parameter using a type switch and returns appropriate errors for nil or invalid connectors in the default case, so additional nil checks are not needed before calling this function.

pkg/cli/lambda_server__added.go (4)

97-101: LGTM: Proper context propagation for connector config client.

The change from ctx to runCtx ensures that the enriched context with logging fields and telemetry setup is properly propagated to the connector config service client.

---

107-107: LGTM: Consistent context usage maintained.

Using runCtx here maintains consistent context propagation from the previous call, ensuring logging and telemetry context is available for the config retrieval operation.

---

181-181: LGTM: Enriched context for connector registration.

Passing runCtx to connector registration ensures critical connector operations have access to proper logging fields and telemetry context, which is essential for debugging and monitoring.

---

183-183: Excellent: Core context propagation to Lambda handler.

This change is the key to enabling context logger usage in AWS Lambda as stated in the PR objectives. By using StartWithOptions with WithContext(runCtx), the enriched context with logging and telemetry setup is now available throughout the entire Lambda execution lifecycle.
