I am trying to submit Temporal workflow using a springboot application, and i am using docker compose.

Creating the stub using below code

WorkflowServiceStubsOptions workflowServiceStubsOptions = WorkflowServiceStubsOptions.newBuilder()
            .setTarget(temporalServerUrl).build();
WorkflowServiceStubs.newServiceStubs(workflowServiceStubsOptions);

‘temporalServerUrl’ is the property passing to the docker file as property name as ‘temporal.server.url’

Below is the snippet of compose file

version: "3.5"
services:
  temporal:
    container_name: temporal
    depends_on:
      - postgresql
    environment:
      - DB=postgresql
      - DB_PORT=5432
      - POSTGRES_USER=temporal
      - POSTGRES_PWD=temporal
      - POSTGRES_SEEDS=postgresql
      - DYNAMIC_CONFIG_FILE_PATH=config/dynamicconfig/development-sql.yaml
    image: temporalio/auto-setup:${TEMPORAL_VERSION}
    networks:
      - temporal-network
    ports:
      - 7233:7233
    volumes:
      - ./dynamicconfig:/etc/temporal/config/dynamicconfig
    labels:
      kompose.volume.type: configMap
  temporal-ps-wf-submit:
    container_name: temporal-ps-wf-submit
    depends_on:
      - temporal
    environment:
      - TEMPORAL_ADDRESS=temporal:7233
      - TEMPORAL_CORS_ORIGINS=http://localhost:3000
      - temporal.server.url=temporal:7233
    image: postgres-workflow-client:1.0.0
    networks:
      - temporal-network
    ports:
      - 8181:8181
    stdin_open: true
    tty: true

When run the compose file, it is showing below error.
