Keto parse and create policies throwing unknown error

[HadiSDev]

Hi I need some help with keto self hosted. After setting up my keto container I serve it the keto yaml file:

version: v1.3.0
# Overridden by the DSN environment variable in docker-compose.local.yml.
dsn: postgres://postgres:postgres@postgres:5432/keto?sslmode=disable

log:
  level: debug

namespaces:
  - id: 0
    name: organization
  - id: 1
    name: project
  - id: 2
    name: file

serve:
  read:
    host: 0.0.0.0
    port: 4466
  write:
    host: 0.0.0.0
    port: 4467

To my docker compose:

services:
  postgres:
    image: postgres:18
    restart: unless-stopped
    environment:
      POSTGRES_DB: flex_annotate
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
    ports:
      - "5432:5432"
    volumes:
      - postgres_data:/var/lib/postgresql
      - ./docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d:ro
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U postgres -d flex_annotate"]
      interval: 5s
      timeout: 5s
      retries: 5

  keto:
    image: oryd/keto:v25.4.0
    restart: unless-stopped
    depends_on:
      keto-migrate:
        condition: service_completed_successfully
      keto-namespace-migrate:
        condition: service_completed_successfully
    ports:
      - "4466:4466" # read
      - "4467:4467" # write
    environment:
      - DSN=postgres://postgres:postgres@postgres:5432/keto?sslmode=disable
      - LOG_LEVEL=debug
      - KETO_READ_URL=http://localhost:4466
      - KETO_WRITE_REMOTE=127.0.0.1:4467
      - POLICIES_FILE=/etc/config/keto/policies.rts
    entrypoint: ["/bin/sh", "-c"]
    command: >-
      "keto serve -c /etc/config/keto/keto.yml &
      KETO_PID=$!;
      /etc/config/keto/init.sh;
      wait $KETO_PID"
    volumes:
      - type: bind
        source: ./keto
        target: /etc/config/keto
        read_only: true

volumes:
  postgres_data:

And I start the service with this shell:

#!/usr/bin/env sh
set -euo pipefail

READ_URL=${KETO_READ_URL:-http://localhost:4466}
WRITE_REMOTE=${KETO_WRITE_REMOTE:-127.0.0.1:4467}
POLICIES_FILE=${POLICIES_FILE:-/etc/config/keto/policies.rts}

# Wait for Keto to be ready
for i in $(seq 1 90); do
  if wget -qO- "$READ_URL/health/ready" >/dev/null 2>&1; then
    break
  fi
  sleep 1
  if [ "$i" -eq 90 ]; then
    echo "Keto not ready after 90s" >&2
    exit 1
  fi
done

echo "Seeding relation tuples from $POLICIES_FILE to $WRITE_REMOTE"
if keto relation-tuple parse "$POLICIES_FILE" --format json \
  | keto relation-tuple create - --insecure-disable-transport-security --write-remote "$WRITE_REMOTE" >/dev/null; then
  echo "Successfully created tuple"
else
  echo "Encountered error"
  exit 1
fi

But whenever I run:

keto relation-tuple parse /etc/config/keto/policies.rts --format json | keto relation-tuple create - --insecure-disable-transpo
rt-security --write-remote 127.0.0.1:4467

I get the following issue:

Error doing the request: rpc error: code = NotFound desc = The requested resource could not be found

I have no idea why because I followed the online guides as best as I could. What am I doing wrong.
