I also reproduction for this issue with APISIX `3.16.0` in `standalone` YAML
mode. The important conditions are `enable_admin: false`, `proxy_mode:
"http&stream"`, YAML config provider, `stream_proxy.tcp`, and an xRPC Redis
`stream_route`.
`docker-compose.yaml`:
```yaml
name: issue-13325
services:
apisix:
image: apache/apisix:3.16.0-debian
container_name: issue-13325-apisix
restart: "no"
volumes:
- ./config.yaml:/usr/local/apisix/conf/config.yaml:ro
- ./apisix.yaml:/usr/local/apisix/conf/apisix.yaml:ro
ports:
- "19080:9080"
- "19101:9101"
- "19090:9090"
```
`config.yaml`:
```yaml
apisix:
node_listen:
- 9080
enable_admin: false
proxy_mode: "http&stream"
stream_proxy:
tcp:
- 9101
xrpc:
protocols:
- name: redis
deployment:
role: data_plane
role_data_plane:
config_provider: yaml
control:
ip: 0.0.0.0
port: 9090
```
`apisix.yaml`:
```yaml
stream_routes:
- id: 1
server_port: 9101
protocol:
name: redis
upstream:
type: roundrobin
nodes:
"127.0.0.1:6379": 1
#END
```
Reproduction steps:
```sh
docker compose up -d
docker compose exec -T apisix apisix version
docker logs --since 5m issue-13325-apisix 2>&1 | rg -n 'unknown protocol
\[redis\]|property "faults"'
docker compose down
```
Observed APISIX version:
```text
3.16.0
```
Observed error:
```text
[error] ... [lua] config_yaml.lua:333: failed to check item data of
[stream_routes] err:unknown protocol [redis] ...
```
A real Redis upstream is not required for this reproduction because the
failure happens while APISIX loads and validates `apisix.yaml`, before any TCP
traffic is proxied to the upstream. In this setup, `proxy_mode: "http&stream"`
starts both HTTP and stream worker initialization paths. The YAML provider is
initialized in the HTTP worker as well, so the HTTP worker validates
`stream_routes`. However, with `enable_admin: false`, the HTTP-side xRPC
initialization returns before registering the Redis protocol schema, so
validating `protocol.name: redis` fails with `unknown protocol [redis]`.
