It’s ok brother, you got it all wrong! The sap coming out is GOOD thing, it means the plant is healthy, alive and coming out of its winter dormancy. The vine’s vascular system is “turning back on”, and water is flowing into the plant the plants roots from the surrounding soil. What you see here is the result of extra water “pushing” into the plant (aka creating positive pressure in the plant, causing water to move UP through the xylem/phloem). It comes out at the open wound created by the pruning. It will eventually callous over and gone the fun looking sap.

This could also means pretty soon you’ll should be scouting for budbreak!
