Troubleshooting

This is a list of common pitfalls on using API Platform, and how to avoid them.

Docker Toolbox is not supported anymore by API Platform. Please upgrade to Docker for Windows.

If the app container cannot start and display this Error starting userland proxy: Bind for 0.0.0.0:80, it means that port 80 is already in use.

You can change the port to be used in the docker-compose.yml file (default is port 80).

By default, JMS Serializer Bundle replaces the serializer service by its own. However, API Platform requires the Symfony serializer (and not the JMS one) to work properly. Fortunately, this behavior can be deactivated using the following configuration:

# api/config/packages/api_platform.yaml

jms_serializer:    
    enable_short_alias: false
