PPM passed wrong object type to the application

[CvekCoding]

Hello!
I use Symfony 4.1 with Api-platform on top. When I launch it through ppm (ppm is in docker) the api-platform crashes with the following stack:

phppm_1     | string(5880) "TypeError: json_decode() expects parameter 1 to be string, object given in /var/www/vendor/api-platform/core/src/GraphQl/Action/EntrypointAction.php:86

Here is a code near of 86 row /var/www/vendor/api-platform/core/src/GraphQl/Action/EntrypointAction.php :

        if ('json' === $request->getContentType()) {
            $input = \json_decode($request->getContent(), true);

            if (isset($input['query'])) {
                $query = $input['query'];
            }

Can you advise me how to fix this? Thanks.

The json_decode error says it all. Could you add a var_dump on the result of $request->getContent()?

[CvekCoding]

@andig It's not looks like a bug of Symfony or Api-platform - this code works with other php processors like php-fpm and apache-php.

This is a serialization of $request->getContent():

RingCentral\Psr7\BufferStream Object
(
    [hwm:RingCentral\Psr7\BufferStream:private] => 29
    [buffer:RingCentral\Psr7\BufferStream:private] => {"query":"","variables":null}
)

[andig]

Thats what I has supected. Psr7, not Symfony httphernel. How are you starting ppm?

[andig]

Nevermind. Could you try casting body to string in the kernel bridge?

[CvekCoding]

@andig I start it through docker-compose because php-pm has to be able to fetch data from DB which is in docker too. This is my config:

...
    phppm:
        image: phppm/nginx
        volumes:
            - ./:/var/www
        ports:
            - "8081:80"
        depends_on:
            - postgres
        entrypoint:
            - /bin/bash
            - /etc/app/run.sh
            - --bootstrap=symfony
            - --static-directory=public/
...

Am I doing something wrong?

[CvekCoding]

Could you try casting body to string in the kernel bridge?

@andig Do you mean this place /ppm/vendor/php-pm/httpkernel-adapter/Bridges/HttpKernel.php(90)? Cast $syRequest's content to the string?

[andig]

No, cast the getBody result in
https://github.com/php-pm/php-pm-httpkernel/blob/master/Bridges/HttpKernel.php#L197 to string. The should fetch the stream contents.

[CvekCoding]

@andig Thanks, it helped:
$syRequest = new $class($query, $post, $attributes = [], $_COOKIE, $uploadedFiles, $_SERVER, $psrRequest->getBody()->getContents());
