Why does my URL redirect say 'Target is invalid'?

[olgaleviz]

I have two pages: one is the old version, the other is the new version of the same product. I want to redirect users from the old version to the new one. When I am trying to create this redirect in Shopify URL redirect but there is an error: “Target is invalid”
