How do you transfer money from PrepaidDigitalSolutions Wallet to PayPal?

So recently I got a card from Salad for $20 that gave me a $20 Visa Card on Prepaid Digital Solutions.
I created a wallet and I want to transfer that money to PayPal. When I do so, I get an error "We're sorry. We're not able to process your request right now. Please try again later."

I did try again later but ended up receiving the same error message. What is a good way to transfer the money?
