Downloaded the static release binary to serve gRPC ext_authz for the gateway in a local end-to-end run. It parsed the JSON-RPC body into parsed_body as expected.
- What worked
- Single static binary, easy to download and run; console decision logs made it possible to see the exact input.
- What got in the way
- The input used camelCase field names for the metadata context rather than the snake_case names in the Envoy-style docs, so every request was denied until I dumped decision logs and adjusted the policy. Only gRPC is supported, not HTTP ext_authz.
