You must install Twig (which is part of the API Platform pack if you run composer require api) to use the HTML format.

OK thank you for your reply. I confirm that resolve my issue.

WARNING : I had when installed API-Platform with 'composer require api' which not provide api-platform/core package. There seems to be some confusion about API-Platform installation process on your website because the first page suggests 'composer require api-platform/core' while the recommends 'composer require api'.
