TextureLoader from Wordpress ACF image

Hi Guys,

I have a website in Wordpress where I have a script that preloads textures from each ACF image field from repeater field. I use shadermaterial and create meshes from textures and shadres. Problem is that sometimes some images not loading properly(colored stripes instead image, as shown on uploaded images) . When I refresh page it sometimes loads ok and sometimes not. There are 10 meshes on a page and they load incorrect randomly.
I assume that problem is that images are loaded from Wordpress ACF. Does anyone know how to fix this?

Is there anyone experienced in working with graphics loaded from WP and Three.js? I spent so many days on that and have no idea how to fix it:(
