manifest unknown

I have tried last week to run a docker-compose on my computer to connect my Python code.

$ version: '3.6'
services:
  python:
    build:
      context: .  # This should point to the directory containing your Dockerfile
    container_name: influxdb_ki
    restart: always
    ports:
      - "80:80"
    depends_on:
      - influxdb  # Ensure your app starts after InfluxDB
    networks:
      - monitoring
    image: mydockerhub/projectname:python-service  # Replace with your Docker Hub username and repo

  grafana:
    image: grafana/grafana  # Correct image name
    container_name: grafana
    restart: always
    ports:
      - "3000:3000"
    networks:
      - monitoring
    volumes:
      - grafana-volume:/var/lib/grafana

  influxdb:
    image: mydockerhub/projectname:influxdb-service  # Replace with your Docker Hub username and repo
    container_name: influxdb
    ports:
      - "8087:8086"
    networks:
      - monitoring
    volumes:
      - influxdb-volume:/var/lib/influxdb
    environment:
      - INFLUXDB_DB=mydb
      - INFLUXDB_ADMIN_USER=admin
      - INFLUXDB_ADMIN_PASSWORD=adminpass
      - INFLUXDB_USER=user
      - INFLUXDB_USER_PASSWORD=password
      - INFLUXDB_INIT_MODE=setup
      - INFLUXDB_INIT_ORG=sth
      - INFLUXDB_INIT_BUCKET=sth
      - INFLUXDB_INIT_RETENTION=myretention
      - INFLUXDB_ADMIN_TOKEN=myadmintoken
    restart: always
networks:
  monitoring:
volumes:
  grafana-volume:
    external: true
  influxdb-volume:
    external: true

this code worked last week but when I tried to change the python code and do the same process I am receiving the following error:
sudo docker-compose up
Pulling influxdb (mydockerhub/projectname:influxdb-service)...

ERROR: manifest for mydockerhub/projectname:influxdb-service not found: manifest unknown: manifest unknown

Please help me to find out how can I
