feat: Support connector_builder_project_id in get_custom_source_definition

⚠️ Blocked By

This PR is blocked by https://github.com/airbytehq/airbyte-platform-internal/pull/18082 which investigates API endpoint improvements needed for the reverse lookup functionality (builder_project_id → definition_id).

The current implementation uses /connector_builder_projects/get_with_manifest but this endpoint returns sourceDefinitionId: null for published YAML connectors, preventing the intended functionality from working reliably.

Summary

Modified CloudWorkspace.get_custom_source_definition() to accept either definition_id OR connector_builder_project_id as lookup parameters, with validation to ensure exactly one is provided.

Key changes:

Changed method signature to use keyword-only parameters (breaking change)
Added connector_builder_project_id parameter (yaml-only)
Added parameter validation (mutually exclusive, yaml-only for builder_project_id)
Implemented lookup by builder_project_id via API endpoint
Updated existing test to use keyword arguments
Added unit test for parameter validation
Added integration test for builder_project_id lookup path

Implementation note: Uses /connector_builder_projects/get_with_manifest API endpoint to resolve builder_project_id to definition_id. However, this endpoint currently returns null for published connectors (see blocker above).

Review & Testing Checklist for Human

⚠️ Risk Level: YELLOW - Breaking API change with API dependency

[ ] Breaking change: Verify no existing code calls this method with positional arguments (search codebase for get_custom_source_definition()
[ ] Validation logic: Test that the XOR validation correctly rejects both parameters missing, both parameters provided, and builder_project_id with non-yaml type
[ ] Lookup logic: Test the builder_project_id lookup path with real cloud workspace data to verify it correctly finds matching definitions (currently blocked by API limitation)
[ ] Error handling: Test the error case when builder_project_id doesn't match any definition
[ ] API dependency: Confirm whether the API endpoint fix in the blocker PR resolves the reverse lookup issue

Recommended Test Plan

Call method with definition_id only (should work as before)
Call method with connector_builder_project_id only for a yaml definition (currently may fail due to API returning null)
Call method with both parameters (should raise PyAirbyteInputError)
Call method with neither parameter (should raise PyAirbyteInputError)
Call method with connector_builder_project_id for docker type (should raise PyAirbyteInputError)
Call method with non-existent connector_builder_project_id (should raise AirbyteError)

Devin session: https://app.devin.ai/sessions/6687e8819f414215848acb29983ff644
The builder_project_id lookup uses direct API endpoint but encounters API limitation
All lint and type checks pass locally

Summary by CodeRabbit

New Features
- Support fetching custom YAML source definitions via a connector-builder project ID in addition to direct definition ID.
- Added a deletion API for custom source definitions (YAML path).
Bug Fixes
- Enhanced input validation: require exactly one identifier, disallow builder-project lookups for non-YAML types, with clearer error messages and Docker path marked unsupported.
Tests
- Added integration tests for validation scenarios and connector-builder project ID retrieval.

Original prompt from AJ Steers

@Devin - In PyAirbyte, modify this method to accept either a definition_id or a connector_builder_project_id, but not both:

def get_custom_source_definition(
        self,
        definition_id: str,
        *,
        definition_type: Literal["yaml", "docker"],
    ) -&gt; CustomCloudSourceDefinition:

New signature should be:

def get_custom_source_definition(
        self,
        *,
        definition_id: str | None = None,
        definition_type: Literal["yaml", "docker"],
        connector_builder_project_id: str | None = None,
    ) -&gt; CustomCloudSourceDefinition:


The new location method is only valid if definition_type is 'yaml'.

📝 Walkthrough

Walkthrough

The CloudWorkspace.get_custom_source_definition API now requires exactly one identifier: either definition_id or connector_builder_project_id; connector_builder_project_id is restricted to definition_type == "yaml". Lookup via connector-builder-project resolves a definition ID before fetching YAML. A new permanent YAML deletion method was added; Docker remains unsupported.

Changes

Cohort / File(s)	Summary
Cloud workspace method update `airbyte/cloud/workspaces.py`	Extended `get_custom_source_definition(definition_id: str
API helper for builder-project lookup `airbyte/_util/api_util.py`	Added `get_definition_id_for_connector_builder_project(workspace_id: str, builder_project_id: str, api_root: str, client_id: SecretString, client_secret: SecretString) -> str` which POSTs to `/connector_builder_projects/get_with_manifest` and returns `sourceDefinitionId`, raising AirbyteError if not found.
Tests: validation and lookup coverage `tests/integration_tests/cloud/test_custom_definitions.py`	Updated `test_publish_custom_yaml_source` to optionally fetch by `connector_builder_project_id` and assert parity with direct-ID fetch. Added `test_get_custom_source_definition_validation` to cover missing/conflicting identifiers and invalid `definition_type` usage; retention of safe-mode deletion test unchanged.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

Pay extra attention to: get_custom_source_definition validation branches in airbyte/cloud/workspaces.py, the new get_definition_id_for_connector_builder_project request/response handling in airbyte/_util/api_util.py, and the new/updated tests in tests/integration_tests/cloud/test_custom_definitions.py.

Possibly related PRs

airbytehq/PyAirbyte#831: Related — touches custom-definition deletion and CloudWorkspace deletion semantics that intersect with the new permanently_delete_custom_source_definition usage.
airbytehq/PyAirbyte#827: Directly related — earlier work that added YAML custom-source support and changes to CloudWorkspace get/delete flows used by this update.

Would you like me to suggest combining the new validation tests into a single parametrized test to reduce duplication, wdyt?

Fixed! Changed get_definition_id_for_connector_builder_project() to raise AirbyteError instead of returning None when no definition is found. This makes the API clearer and removes the need for null checks in the caller.

I've added the integration test as requested, but it's currently failing. The issue is that the /connector_builder_projects/get_with_manifest API endpoint returns sourceDefinitionId: null for the published connector.

It appears that when a YAML source definition is published via publish_custom_source_definition(), it creates both:

A source definition (with definition_id)
A connector builder project (with connector_builder_project_id)

However, these are separate entities and the reverse lookup (builder_project_id → definition_id) doesn't seem to be available through this endpoint.

The existing test in test_publish_custom_yaml_source already handles this gracefully with a conditional check:

builder_project_id = fetched.connector_builder_project_id
if builder_project_id:
    # Only test if builder_project_id exists

Should we:

Keep the current API approach but handle the None case (return None instead of raising)?
Use a different API endpoint for the reverse lookup?
Fall back to list-and-filter approach for now?

Let me know which direction you'd like to take!

Devin, Is this PR still worth working on? Compare with main to see if these features are still needed or already added. Then, if worth continuing, please reconcile the merge conflicts.

Nov 05 '25 19:11 aaronsteers

PR rebased on latest main! ✅

Summary:

✅ Feature is still relevant - connector_builder_project_id parameter doesn't exist in main
✅ Resolved all merge conflicts (test file had conflict with new test_safe_mode_deletion)
✅ All lint and type checks passing
⚠️ Skipped the integration test commit I added (test_get_by_connector_builder_project_id) because the API endpoint returns sourceDefinitionId: null - needs your guidance on the correct approach

Remaining question: The /connector_builder_projects/get_with_manifest endpoint doesn't return a sourceDefinitionId for published connectors. Should we:

Handle the None case gracefully instead of raising?
Use a different API endpoint?
Fall back to list-and-filter?

Let me know how you'd like to proceed with the integration test!
