HI,
I get the following error:
Fatal error: Uncaught LogicException: setProjectDir() must be called to initialize the ContaoKernel. in /vendor/contao/manager-bundle/src/HttpKernel/ContaoKernel.php on line 64

Here ist the Call Stack

Installed via composer, got no error...

Thank you for your help!

When in replace FrontendApi Line 30
$kernel->setRootDir(dirname(DIR).'/app');
with
ContaoKernel::setProjectDir(dirname(DIR).'/app');

on line 28, this problem is solved.
Then i get

Fatal error: Uncaught InvalidArgumentException: Composer installed.json was not found at ".../vendor/dieschittigs/contao-content-api/app/vendor/composer/installed.json" in .../vendor/contao/manager-plugin/src/PluginLoader.php on line 134

Thanks for the report! Must be something with the latest Contao Version, I'll look into it

I'm currently migrating the code into a Symfony Bundle. This should be fixed with the next release
