Unfortunately EPROLO support was not helpful, but despite this obvious error in their plugin, the synchronisation of orders with Woocommerce works.
Of course, if you’re developing a site for a client or to sell it, it’s not nice… but I repeat, it works. I have received orders and the whole automated process worked.
I hope they release an update that fixes this error – at this point only display error but confusing to the user.
