Failed to parse RunInTerminalRequestArguments

Error message

Failed to parse RunInTerminalRequestArguments

What it means

The debug adapter sent a runInTerminal request whose arguments could not be deserialized into RunInTerminalRequestArguments (schema mismatch or malformed payload). The session responds with a failure to the client and surfaces this error.

Solutions

1. Check the adapter version — its runInTerminal arguments may not match the DAP structs expected here
2. Update or pin a compatible debug adapter version
