decode host auth get runtime request: %w

Error message

decode host auth get runtime request: %w

What it means

The host-side auth.get_runtime RPC callback failed to decode its request into rpcHostAuthGetRequest — invalid JSON or wrong field types. The runtime-info call is rejected before the auth manager is consulted.

Solutions

1. Validate the exact bytes sent for the runtime call (must decode into an object with a string auth_index)
2. Align plugin and host pluginapi versions and rebuild the plugin
3. Use SDK helpers for the RPC; restart the plugin process if the channel is desynced

payload, err := json.Marshal(map[string]string{"auth_index": idx})
if err != nil { return err }
if idx == "" { return errors.New("auth_index required for runtime info") }

When it happens

Trigger: Plugin calls the host 'auth get runtime' RPC with a payload that is not valid JSON or where auth_index has the wrong type/name; identical failure class to auth.get decode but on the runtime variant.

Common situations: Plugin SDK protocol drift; hand-built RPC frames with typos; partially-written frames over stdio/socket transport.
