Nova API Route returning 301 redirect ONLY in production, works locally

I have a tool in Nova that lets a user toggle a resource model (in this specific case, a 'document') as a favorite. this feature is part of a larger tool, and all other aspects of the tool work (routing, getting the data, etc). The favorite toggling sends a post request to the server with the UUID of the model. Then, the ApiController returns a json response. Nothing in it seems to suggest it would encounter a redirect, but for some reason, in production, the button, when clicked, triggers a POST request to the route, which then redirects back to the same route with a GET request. It's very strange and I haven't been able to isolate the cause.

This is the method that handles toggling the Favorite item in Vue:

<script>
import {HeartIcon} from '@heroicons/vue/24/outline';
import {HeartIcon as HeartIconFill} from '@heroicons/vue/24/solid';
import {IconButton} from 'ecsc-ui';

export default {
    name: "Favorite",
    components: {
        IconButton,
        HeartIcon,
        HeartIconFill,
    },
    props: {
        model: {
            type: Object,
            required: true,
        },
    },
    methods: {
        favorite() {
                    Nova.request().post('/nova-vendor/vault/api/toggle-favorite-document/', {uuid: this.model.uuid}
                    ).then(response => {
                        this.message = response.data.message;
                        Nova.success(this.message);
                        this.model.isFavorite = !this.model.isFavorite;
                    }).catch(error => {
                        Nova.error('Error: Could not handle favorites.');
                    });
            }
        },
    }
}
</script>
<template>
    <IconButton
        v-if="this.model.isFavorite"
        color="light"
        tooltip="Add to Favorites"
        @click="favorite()"
    >
        <HeartIconFill class="w-6 h-6 text-red-800"/>
    </IconButton>
    <IconButton
        v-else
        color="light"
        tooltip="Add to Favorites"
        @click="favorite()"
    >
        <HeartIcon class="w-6 h-6"/>
    </IconButton>
</template>

here is the route's definition:

Route::post('/toggle-favorite-document/', [VaultApiController::class, 'toggleFavoriteDocument']);

here is the VaultApiController@toggleFavoriteDocument method:

public function toggleFavoriteDocument(NovaRequest $request): JsonResponse
    {
        //first, validate the request 
        $data = VaultRequest::validateFavoriteDocument($request->all())->validated();

        //then, get the document
        $document = Document::where('UUID', $data['uuid'])->first();

        //now, get the user
        $user = Auth::user();

        //toggle the favorite
        $user->favoriteDocuments()->toggle($document);

        //get the favorites ids
        $favoriteDocumentIds = $user->favoriteDocuments->pluck('id')->toArray();

        //if the document exists in favorites now, then it was just added
        //if it doesn't exist in favorites now, then it was just removed
        if (in_array($document->id, $favoriteDocumentIds)) {
            $message = 'Added to favorites.';

            return response()->json([
                'message' => $message,
                'isFavorite' => true,
            ]);
        } else {
            $message = 'Removed from favorites.';

            return response()->json([
                'message' => $message,
                'isFavorite' => false,
            ]);
        }
    }

In the Network tab of Chrome's inspection tool, I see this:

Name                                     | Status | Type               | Initiator                                  | Size     | Time 
toggle-favorite-document/ | 301      | xhr/Redirect | vault:2                                    | 288 B  | 856 ms
toggle-favorite-document/ | 405      | xhr                 | toggle-favorite-document/  | 9.3 kB | 515 ms

The issue you're encountering, where a POST request is being redirected with a 301 status code, is often related to URL misconfigurations or server settings. Here are a few steps to diagnose and resolve the issue:

Check Trailing Slashes in Routes: Ensure that the route definition in your web.php or api.php file does not have a trailing slash. Laravel routes should not end with a trailing slash.
```
Route::post('/toggle-favorite-document', [VaultApiController::class, 'toggleFavoriteDocument']);
```
Check for URL Rewriting Rules: If you're using a web server like Apache or Nginx, ensure that there are no URL rewriting rules that might be adding a trailing slash or redirecting POST requests.

For Apache, check your .htaccess file for any rules that might be causing this behavior.

For Nginx, check your server configuration files.
Check for Middleware: Ensure that there are no middleware in your Laravel application that might be causing the redirect. Middleware can sometimes modify requests and responses, leading to unexpected behavior.
Check for Caching: Sometimes, caching mechanisms (like Cloudflare or other CDNs) can cause redirects. Ensure that your caching settings are not interfering with your API routes.
Check for Environment Differences: Since the issue only occurs in production, there might be differences in your environment configurations. Check your .env file and ensure that all relevant configurations are consistent between your local and production environments.

Debugging: Add some logging to your toggleFavoriteDocument method to see if the request is reaching the controller and if any unexpected behavior is occurring.

public function toggleFavoriteDocument(NovaRequest $request): JsonResponse
{
    \Log::info('toggleFavoriteDocument called', ['request' => $request->all()]);

    //first, validate the request 
    $data = VaultRequest::validateFavoriteDocument($request->all())->validated();

    //then, get the document
    $document = Document::where('UUID', $data['uuid'])->first();

    //now, get the user
    $user = Auth::user();

    //toggle the favorite
    $user->favoriteDocuments()->toggle($document);

    //get the favorites ids
    $favoriteDocumentIds = $user->favoriteDocuments->pluck('id')->toArray();

    //if the document exists in favorites now, then it was just added
    //if it doesn't exist in favorites now, then it was just removed
    if (in_array($document->id, $favoriteDocumentIds)) {
        $message = 'Added to favorites.';

        return response()->json([
            'message' => $message,
            'isFavorite' => true,
        ]);
    } else {
        $message = 'Removed from favorites.';

        return response()->json([
            'message' => $message,
            'isFavorite' => false,
        ]);
    }
}

By following these steps, you should be able to identify and resolve the issue causing the 301 redirect in your production environment.

@LaryAI It was the trailing /. I didn't know that would trigger a redirect in production. Lesson learned!
