This error ("Error fetching embeddings: 422") is new in GitHub.copilot-chat v0.50.2026052102 — not present in the v0.49.0 baseline. The error occurs during computeEmbeddings → _getPredictedTools, suggesting a 422 response from the embeddings API endpoint during tool prediction.

Partial deminification (1/4 frames mapped): one frame resolves to editFileHealing.tsx:404 (likely a shared fetch utility). Three frames at lines 7120/7142 did not map — these likely correspond to the embeddings and tool prediction modules.
