Which LSP client (editor/plugin) do you use?

Haskell v2.2.2
https://marketplace.visualstudio.com/items?itemName=haskell.haskell

Which version of HLS do you use and how did you install it?

see above

Have you configured HLS in any way (especially: a hie.yaml file)?

no

Steps to reproduce

Eval-plugin: Evaluate -- >>> does not work (in some cases) when there is one or more newlines at end of the file. Also, only if the -- >>> is AFTER the function definition. It works when its before

myProduct :: Num p => [p] -> p
myProduct [] = 1
myProduct (n:ns) = n * myProduct ns

-- >>> there is no evaluate

{-
myProduct [2,3,4]
= {???}
???
...
-}

Expected behaviour

Evaluate does work with newline at end

Actual behaviour

Evaluate does not work with newline at end

This issue has been fixed by #4113
The fix is probably going to be included in the next release of hls (2.8.0.0?)
