Error when registering transformer

[agentphoenix]

I'm trying to get transformers working and I keep getting an error exception that the delimiter is empty. I've tracked this down to the registration of the transformer in the service provider and when I dump the $app['config']['api::embeds'] I get an empty array instead of what's in the config file. (I did a fresh config:publish just to be sure.) Any reason why the service provider wouldn't be able to grab those config values?

Running the latest version?

[agentphoenix]

Yep, just did a composer update last night. My lock file says 0.2.4.

[jasonlewis]

Can you paste the full exception stack trace please.

Having a hard time reproducing this. Only thing I can think of is it being on Windows as I've not tested it at all in a Windows environment. Can you try dumping out other configuration items and see if they're loaded correctly?

[agentphoenix]

I just tried to dump the version number out of the config file in the service provider's boot and register methods.

In boot, I get the v1 string out of the config file like expected.

In register, I get an empty array.

For whatever reason, the API config file doesn't seem to be available in register. Not sure what about Windows would be causing that issue though as it's a pretty straightforward operation.

[jasonlewis]

No it shouldn't be possible to call it inside register, but it's safe to do so inside a binding as they shouldn't be called until the application has booted.

Okay so this doesn't produce anything for you?

$this->app['dingo.api.transformer'] = $this->app->share(function($app)
{
    dd($app['config']['api::embeds']);
    return new Transformer(new Fractal, $app, $app['config']['api::embeds.key'], $app['config']['api::embeds.separator']);
});

Dumping other config keys there produce anything?

[agentphoenix]

Nothing, just an empty array no matter which of the values I try to dump.

[jasonlewis]

But you can dump the exact same thing (api::embeds) in the boot method with no worries at all?

[agentphoenix]

In boot, I can dump api::embeds and get an array (or any of the other items in the API config file), but when I try to dump api::embeds.key it comes back NULL. The only way for me to get the key directly is ['config']['api::embeds']['key'].

Strangely enough, grabbing other nested array items doesn't have the same issue (like rate_limiting.exceeded).

[jasonlewis]

I've had a go at this on Windows and am still unable to reproduce. Sorry, not much more I can do here I don't think.

[agentphoenix]

No biggie. I'll have to keep digging through things and see if I can figure it out. Thanks for your help!
