Error when running process 'Products Data Entry (Jasper)'

Issue

When running the process Products Data Entry (Jasper) in a Manufacturing Order:

• Error: Internal Server Error ... pops up
• Logs in reports container show error containing reports_1 | Caused by: java.net.UnknownHostException: app

Solution:

• Port-Bind the app-container’s api in your docker-compose.yml, e.g.:

  app:
  ...
    ports:
      - "8282:8282"
  

• Update the ad_sysconfig entry API_URL in your database to the server and port which shall be reachable by your clients:

  docker exec -u postgres metasfreshdocker_db_1 psql -d metasfresh -c "UPDATE ad_sysconfig SET value = 'http://my.metasfreshserver.com:8282/api' WHERE name = 'API_URL';"
  

• Restart your instance:

  docker-compose down && docker-compose up -d
  

• Make sure Port 8282/TCP is reachable from your clients, e.g.:

  nc -vz my.metasfreshserver.com 8282
  my.metasfreshserver.com [AAA.BBB.CCC.DDD] 8282 open
  

Background:

In order to print labels, the reports container needs to send requests to the app internal API. Since docker-compose v1 does not allow looping links, the app API needs to be exposed externally for the reports container to reach it.
