Making subscription assignment from admin panel with Laravel Cashier

I want to manage subscriptions through my admin panel. I want to assign a subscription to the user I want, manage the subscription period, or cancel the subscription. (I use Cashier Stripe) But no matter what I did, I couldn't complete it and I kept getting different errors. I get the following error very often and cannot start a subscription.

The customer's location isn't recognized. Set a valid customer address in order to automatically calculate tax.

// Subscription and Plan
$newPlanId = $request->input('subscription');
$expiresAt = $request->input('expires_at') ? Carbon::parse($request->input('expires_at')) : null;

// Get stripe_price id
$stripePlanId = $newPlanId ? SubscriptionPlan::find($newPlanId)->stripe_id : null;

if ($newPlanId) {
    if (!$user->hasStripeId()) {
        $user->createAsStripeCustomer();
    }

    if ($user->subscribed('default')) {
        if ($user->subscription('default')->stripe_plan != $stripePlanId) {
            if ($user->subscription('default')->canceled()) {
                $user->newSubscription('default', $stripePlanId)->trialUntil($expiresAt)->create(null);
            } else {
                $user->subscription('default')->swap($stripePlanId);
            }
        }
    } else {
        $user->newSubscription('default', $stripePlanId)->trialUntil($expiresAt)->create(null);
    }

    if ($expiresAt) {
        $user->subscription('default')->update(['trial_ends_at' => $expiresAt]);
    }
}

if (is_null($newPlanId) || $newPlanId === '0') {
    $user->subscriptions()->each(function ($subscription) {
        $subscription->cancelNow();
    });

    $user->subscription('default')->update(['trial_ends_at' => $expiresAt]);
}
