BelongsTo field throws "Trying to get property of non-object" error.

I've been working on implementing this in a new project I'm working on and so far it's been great! However, I'm running in an issue when trying to add a nested form which uses a BelongsTo field.

The specific error I'm getting is happening happening within the index function of laravel/nova/src/Http/Controllers/AssociatableController.php, specifically at line 23. As far as I can tell, the $field variable is returning null because the Nova isn't able to find the resource.

I've been digging around a bit and I believe the issue is being cause by an incorrectly formatted API call to the /nova-api/RESOURCE/associatable endpoint. When I load the resource through a nested form, it tries to call the API at /nova-api/admission-referral-informations/associatable/nested:referralInformation[county] (which throws a 500 error), but when I load the resource as a standard Nova relationship field, it calls the API at /nova-api/admission-referral-informations/associatable/county (which works).

So basically the nested form uses nested:referralInformation[county] in the URL, when it should actually just be using county. I'll keep digging around to see if I can fix it on my own, but please let me know if you have a better idea of what's going on/if you need more info.

Thanks!

Hi,
Just update the package and remove the Trait (which was responsible for redirecting the API calls) as it’s no longer needed :)

😂 I thought I was on 2.0.0, but I guess not! Thanks a ton!
