Core: Upgrade to dev-master results in "Format 'html' not supported, handler must be implemented"

[Drachenkaetzchen]

Hi,

I just upgraded to dev-master. However, now calls to the Dunglas API return Format 'html' not supported, handler must be implemented. Was there a change which caused this, or is this because I removed NelmioApiDocBundle from my project (which didn't work with dev-master)?

The backtrace shows that this exception is created by FOS\RestBundle\View\ViewHandler. Could this be an interoperability issue in conjunction with the FOSRestBundle?

thanks
Felicitus

Did you set the view_response_listener to force ?

fos_rest:
    view:
        view_response_listener: 'force'

https://github.com/FriendsOfSymfony/FOSRestBundle/blob/832d08199cadf1770ec43c2cba68b42b4d5e7f9f/EventListener/ViewResponseListener.php#L73-L80
Try to set it to true in order to let other view listeners try to do their job when the _view attribute does not exist.

Yes, my config includes view_response_listener:

fos_rest:
    body_listener: true
    format_listener: true
    param_fetcher_listener: force
    format_listener:
        rules:
            - priorities: [json, xml]
            - fallback_format: json
    view:
        exception_wrapper_handler: PartKeepr\DoctrineReflectionBundle\Exception\ExceptionWrapperHandler
        default_engine: php
        formats:
            json: true
            xml: true
        templating_formats:
            html: false
        view_response_listener: force

I'm currently stepping through the debugger, but any hints where the problem could be caused are appreciated!

What happen if you set :

fos_rest:
    body_listener: true
    format_listener: true
    param_fetcher_listener: force
    format_listener:
        rules:
            - priorities: [json, xml]
            - fallback_format: json
    view:
        exception_wrapper_handler: PartKeepr\DoctrineReflectionBundle\Exception\ExceptionWrapperHandler
        default_engine: php
        formats:
            json: true
            xml: true
        templating_formats:
            html: false
-        view_response_listener: force
+        view_response_listener: true

??

Wow, thank you, this works now! Sorry I didn't read your answer as carefully as I should have. I'm not sure why it was set to force in the first place.

I solved this issue by using a pattern to restrict FOSRestBundle to only relevant URLS:

fos_rest:
  # …
  # Do not interfer with API Platform
  zone:
      - { path: ^/FOS_REST_PREFIX/api/* }
