Thanks.

Can you check if you are using the same volume?

This error(appears to me) happens when you have started from scratch. It tries to find an inexistent GraphQL schema.

My docker-compose.yml is as follows.Any problem?

version: “3.2”
services:
zero:
image: dgraph/dgraph:latest
volumes:
- /data/dgraph:/dgraph
ports:
- 5080:5080
- 6080:6080
restart: on-failure
command: dgraph zero --my=zero:5080
alpha:
image: dgraph/dgraph:latest
volumes:
- /data/dgraph:/dgraph
ports:
- 8080:8080
- 9080:9080
restart: on-failure
command: dgraph alpha --whitelist 0.0.0.0/0 --my=alpha:7080 --lru_mb=2048 --zero=zero:5080
ratel:
image: dgraph/dgraph:latest
ports:
- 8000:8000
command: dgraph-ratel

Feels okay. Are you able to reproduce twice?
