I am going to use Symfony Framework 3.3 for API development.
I am following these steps written in this blog: https://www.cloudways.com/blog/rest-api-in-symfony-3-1/
In the first minutes of installment I faced off with a problem.
An error occurred when executing the "'cache:clear --no-warmup'" command:
Fatal error: Uncaught Symfony\Component\Config\Definition\Exception\InvalidConfigurationException: Unrecognized option "fos_rest" under "swiftmailer.mailers.default" in ~/Sites/selfdev/vendor/symfony/symfony/src/Symfony/Component/Config/Definition/ArrayNode. php:317
where I have just copy-pasted this into my config.yml file
# FOSRest Configuration
fos_rest:
body_listener: true
format_listener:
rules:
- { path: '^/', priorities: ['json'], fallback_format: json, prefer_extension: false }
param_fetcher_listener: true
view:
view_response_listener: 'force'
formats:
json: true
what shall I do to get over this error?
