Fix AssertionError
in Instructor
✅ Solution
AssertionError in instructor often arises from mismatches between expected and actual values in validation checks, particularly when dealing with OpenAI/Azure OpenAI responses or Pydantic models. To resolve this, carefully examine the assertion traceback to identify the specific discrepancy, and ensure that the data being validated aligns with the expected schema or type defined within the instructor's code, for example, making sure JSON_SCHEMA mode is an available config setting. Update the code or data to match the expected format or adjust the assertion to accommodate the actual data structure or values.
