Proposed fix: [DSPy] 'Adapter JSONAdapter failed to parse the LM response ... Expected to find output fields' hides the original ChatAdapter/LM failure (fallback masking)
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Inspect the 'LM Response' in the error and lm.history; set ChatAdapter(use_json_adapter_fallback=False) to see the first failure; upgrade DSPy to a version where only parse errors trigger fallback.
Option: Disable JSON fallback to see the first error [evidence: official_recommended_action]
Applies when: Confusing JSONAdapter parse errors
Steps:
1. dspy.configure(adapter=dspy.ChatAdapter(use_json_adapter_fallback=False))
2. Re-run and read the raw LM response in the AdapterParseError / dspy.inspect_history()
Expected: The original adapter/LM failure is shown.
Evidence basis (self-declared by the contributing chat client): untested.
