Livewire array errors not being showed because of php echo lines html

Hi, I found that in an array of items, if one item has an error, it is not shown. This is the php code (gotten with Xdebug)

                            <td class="celda">
                                <?php xdebug_break(); ?>
                                <input type="number" class="form-control form-control-sm"
                                    wire:model.live.debounce.250ms="lineas.<?php echo e($index); ?>.cantidad" />
                                <!--[if BLOCK]><![endif]--><?php $__errorArgs = ['lineas.<?php echo e($index); ?>.cantidad'];
$__bag = $errors->getBag($__errorArgs[1] ?? 'default');
if ($__bag->has($__errorArgs[0])) :
if (isset($message)) { $__messageOriginal = $message; }
$message = $__bag->first($__errorArgs[0]); ?>
                                    <span><?php echo e($message); ?></span>
                                <?php unset($message);
if (isset($__messageOriginal)) { $message = $__messageOriginal; }
endif;
unset($__errorArgs, $__bag); ?><!--[if ENDBLOCK]><![endif]-->

The problem is that in

if ($__bag->has($__errorArgs[0])) :

$__bag is

lineas.0.cantidad:
array(1)
0:
"El campo lineas.0.cantidad debe ser mayor que 0."

And $__errorArgs[0] contains:

lineas.<?php echo e($index); ?>.cantidad"

However, this returns false instead of true, therefore, the error is never shown.

$__bag->has($__errorArgs[0])
false
