State: closed
Merged: No

close #5027

Summary

Adds optional response_schema parameter to interrupt() function and Interrupt dataclass to enable structured validation of resume values in human-in-the-loop workflows.

Changes

  • Core functionality: Added response_schema: dict | None field to Interrupt dataclass
  • API enhancement: Modified interrupt(value, *, response_schema=None) to accept Pydantic model classes
  • Validation: Resume values are validated against the schema and converted to model instances
  • Error handling: Invalid data triggers new interrupts with detailed validation error messages

Technical Details

  • Stores JSON schema dictionaries (not Pydantic classes) for proper serialization
  • Compatible with all checkpointers and graph state persistence
  • Maintains backward compatibility - existing code works unchanged
  • Validation errors include detailed field-level feedback
