With copilot-20260215.918 when I run M-x copilot-login I only get an error

jsonrpc-request: jsonrpc-error: "request id=2 failed:", (jsonrpc-error-code . -32602), (jsonrpc-error-message . "Schema validation failed with the following errors:
- : Expected object"), (jsonrpc-error-data)

This is with @github/copilot-language-server version 1.430.0 already installed.

Logging in worked with copilot-20251210.1016 (and same @github/copilot-language-server version 1.430.0)
