Automate Timeline Based on Start Date Column and Duration

I’d love to have new eyes on this. I tried the general caster solution and it just creates “unexpected errors” and doesnt update anything on the board. Including a screen shot of my board. EndDate is a formula column that adds duration days to start date. I need Timeline to update automatically. And I have a dependencies column, start date changes with that.

Also, screen shot of my general caster integration.
