Summary

  • remove the GotoAction model serializer whose Any return type reduced its Pydantic serialization schema to {}
  • keep unset wait_until compatibility at the SDK/API wire boundaries via exclude_none
  • add a discriminated-union serialization-schema regression test
  • document backward-compatible model and OpenAPI changes for maintainers

This fixes the malformed GotoAction-Output schema consumed by nottelabs/notte-cli#96. After merge, notte-api should bump its pinned Notte revision and deploy staging before regenerating that client.

Validation

  • pytest tests/test_goto_wait_until.py -q (6 passed)
  • pre-commit hooks on all changed files (ruff, formatting, basedpyright, secrets and repository checks)

Summary by CodeRabbit

  • Documentation

    • Added backward-compatibility guidance for API model changes, including validation and serialization schema checks.
    • Added rollout recommendations for introducing optional fields safely.
  • Bug Fixes

    • Updated action serialization so unset optional values are omitted at the API boundary while explicitly configured values remain available.
    • Improved schema handling to preserve concrete action definitions and compatibility with older SDK versions.

Walkthrough

The change removes the custom GotoAction serializer and moves null-field omission to the SDK wire boundary. Tests cover configured and unset wait_until values and verify concrete serialization schemas. Documentation adds API model backward-compatibility guidance for optional fields, schema regression tests, and staged rollout procedures.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 2f4c2

The action schema is restored, but some serialized action results may now include a null wait_until field that older consumers do not accept. Add omission handling at affected output boundaries and cover the published input/output schemas before merging.

Greptile Summary

Removes GotoAction’s model-wide serializer so Pydantic retains a concrete serialization schema while moving omission of unset wait_until values to wire boundaries.

  • Adds regression coverage for the discriminated ActionUnion serialization schema.
  • Updates backward-compatibility guidance for model and OpenAPI changes.
  • Still needs the repository-required integration test covering the generated API contract.

Confidence Score: 4/5

The implementation appears behaviorally sound, but the repository’s backend bug-fix testing requirement must be satisfied before merging.

The direct serialization-schema regression test validates the core model fix, and SDK request boundaries omit null values, but no integration test verifies the generated FastAPI OpenAPI contract affected by the bug.

Files Needing Attention: tests/test_goto_wait_until.py

Important Files Changed

Filename Overview
packages/notte-core/src/notte_core/actions/actions.py Removes the custom GotoAction serializer that caused its serialization schema to collapse to an unconstrained object.
tests/test_goto_wait_until.py Adds useful direct schema coverage but lacks the required integration-level OpenAPI regression test.
docs/backward-compatibility.md Documents wire-boundary omission, concrete serialization schemas, regression testing, and rollout requirements.
docs/CONTRIBUTING.md Links contributors changing API-facing Pydantic models to the new compatibility guide.

### Issue 1
tests/test_goto_wait_until.py:24-25
**Missing Required Integration Test**

This backend bug fix adds only a direct Pydantic schema unit test. The repository requires every backend bug fix to include an integration test, so this requirement must be satisfied before merging. Add coverage of the generated FastAPI OpenAPI document, especially the `GotoAction` input and output components, to verify the client-facing contract.

Preserve omission of unset GotoAction.wait_until.

ExecutionResult.action is an ActionUnion without a serializer. Therefore, default ExecutionResult.model_dump() and StepBundle.model_dump() can emit "wait_until": null for GotoAction(url=...). Preserve _omit_unset_wait_until, or apply an explicit serialization policy at these boundaries.

Add validation and published OpenAPI schema coverage.

The test currently checks only TypeAdapter(ActionUnion).json_schema(mode="serialization"). Add validation-mode coverage and assert concrete GotoAction-Input and GotoAction-Output components in the generated FastAPI OpenAPI document.
