Migrate collection operations from APIHarnessV2 to CustomStorage#118
Conversation
Use CustomStorage service class instead of APIHarnessV2 (Uber class) for
collection CRUD operations. Service class imports enable the Foundry Functions
Editor to auto-detect required OAuth scopes, which is not possible with
Uber class .command() calls.
Changes:
- Replace APIHarnessV2 with CustomStorage(ext_headers=_app_headers())
- Replace .command("PutObject"/"SearchObjects") with .PutObject()/.SearchObjects()
- Add defensive .get() for SearchObjects response body
- Move header construction to _app_headers() helper
Align test mocks with the APIHarnessV2-to-CustomStorage migration in main.py: patch CustomStorage instead of APIHarnessV2, mock individual PutObject/SearchObjects methods instead of .command() side_effect, and verify ext_headers construction instead of per-request headers kwargs.

Add verifyWorkflowExecutionCompleted() that polls the execution status page until terminal state, catching function failures that were previously invisible.

Replaces APIHarnessV2 (Uber class) with CustomStorage (service class) for collection CRUD operations in the log-event function handler.
The Falcon Foundry Functions Editor parses
from falconpy import CustomStorageto auto-detect required OAuth scopes (custom-storage:read,custom-storage:write). It cannot parse the Uber class.command()pattern, which means apps using APIHarnessV2 require manual scope configuration.Changes in log-event/main.py:
APIHarnessV2().command("PutObject", ...)→CustomStorage(ext_headers=...).PutObject(...)APIHarnessV2().command("SearchObjects", ...)→client.SearchObjects(...).get("body", {})for SearchObjects response handlingThe
ext_headersconstructor parameter replaces per-requestheaderskwargs, applying theX-CS-APP-IDheader to all requests from the client instance. Response shapes and behavior are unchanged.Draft because the associated blog post needs updating to match the new patterns.
