haskell - Variable not in scope: endpoints :: Contract s0 T.Text a0

Question

I'm new to Plutus and I'm working through the tutorial but I click on Evaluate I get this error. I'm not sure if this is from the playground or not because I used the same code from their new tutorial .

The error doesn't show up when I compile it only happens when I attempt view transactions by clicking Evaluate. I'm not sure if this is an issue with the code because it passed compile.

The Error message doesn't seem about the code itself. Heck it even errors out with zero transactions on the test block chain. I tried with with different variations on transactions. I know these updates just came out this week. I double checked the documentation.

    ? Perhaps you meant ‘endpoint’ (imported from Language.Plutus.Contract)
