Odd CORS issue

Hi,

I've been developing a API filter/ include relationship logic locally. It's here: https://app.moos.nu/api/v1/installations/?filter[client]=001&includeSensors&includeTracks

This works locally. But not remotely. My API client throws a 500 error, without body returned for the response. In my browser it says "CORS missing allow origin". If I remove the includeSensors and includeTracks bit it does work (feel free to try, I'll keep it open for now). Locally it both works. My cors config is the default as per below.

Any idea? I'm on an EC2 instance at AWS, running on Nginx.

    'paths' => ['api/*', 'graphql'],
    'allowed_methods' => ['*'],
    'allowed_origins' => ['*'],
    'allowed_origins_patterns' => [],
    'allowed_headers' => ['*'],
    'exposed_headers' => [],
    'max_age' => 0,
    'supports_credentials' => true,

It isn't a CORS issue. You're getting a 500 error on the back-end which responses without the proper CORS header.

Check your logs to see what causes the 500 error.

For me, it works if I just remove includeTracks.

I've set environment to development and debug to true, but I'm not seeing any errors....

Thanks for checking that too @mohamedtammam, appreciate it. The code for these two includes seems pretty basic. And I'm thrown off by the fact that it works locally, yet not remote. The relationship exists remotely too, with data.

I'll start Log:debug'ing, while pushing to the prod, but any help still appreciated.

        // Optionally load relationships
        if($request->has('includeSensors') && !$request->has('includeTracks'))
        {
            $installations->with('sensors');
        }

        if($request->has('includeTracks'))
        {
            $installations->with('sensors.tracks');
        }
```

@axtg If that part is what causing the issue, can you please try.

if($request->has('includeSensors') && !$request->has('includeTracks'))
        {
            $installations->with('sensors');
        } else($request->has('includeTracks'))
        {
            $installations->with('sensors.tracks');
        }
