TYPO3 Core

Hello everyone,
I want to use an upload field with multiple in Typo3 Form.
However, when submitting, I get a validation error message.
Is it a bug? Does Form Framework not support upload with multiple? How can I do it?

<formvh:form.uploadedResource
            property="{element.identifier}" 
            as="resource" 
            id="{element.uniqueIdentifier}" 
            class="{element.properties.elementClassAttribute}" 
            errorClass="{element.properties.elementErrorClassAttribute}" 
            additionalAttributes="{formvh:translateElementProperty(element: element, property: 'fluidAdditionalAttributes')}" 
            accept="{element.properties.allowedMimeTypes}" 
            multiple="multiple" 
        >
            <f:if condition="{resource}">
                <div id="{element.uniqueIdentifier}-preview">
                    {resource.originalResource.originalFile.name}
                </div>
            </f:if>
</formvh:form.uploadedResource>
