"No instance for (Default ...) arising from a use of 'def'" errors on editing schema about ihp HOT 5 CLOSED

/Users/simon/.ghci contains:

:def ho \x -> return $ ":!hoogle " ++ x
:def qc \c -> return $ ":m + Test.QuickCheck.Property \nTest.QuickCheck.quickCheck (" ++ c ++ ") \n:m - Test.QuickCheck.Property"
:set stop :list
:def doc \input -> return (":!haskell-docs " ++ input)
:def rr (\a -> return $ unlines [":r", a])

Moving it out of the way didn't make a difference.

Perhaps my #130 workaround is incomplete. Perhaps when we find out why it was needed, this issue will be resolved too.

Hey, thanks for letting us know :)

Could you quickly share the content of /Users/simon/.ghci?

Maybe GHC is loading loading two different package versions for Data.Default. The Default MetaBag instance is defined here in ModelSupport. The module IHP.ModelSupport is one of first imports of build/Generated/Types.hs.

@simonmichael could you check whether that issue still happens? We recently merged a few improvements in isolating the GHC used by the IHP dev server.

@simonmichael could you give it another try, or should we close the issue? :)
