Image Width and Height not showing up

[pindiespace]

Starting in April, I started receiving the following messages: The attribute 'width' in tag 'amp-img' is set to the invalid value ''.

<span class="et_pb_image_wrap "><amp-anim src="https://novyunlimited.com/wp-content/uploads/2019/07/GR-clientfeature-v02.gif" height="" width="" class=" amp-image-tag" alt="" sizes="(min-width: 0px) 0px, 100vw"></amp-anim></span>
</div>

Is there a way to specify width and height correctly so the AMP test works correctly? https://search.google.com/test/amp
