Very similar to this bug for a different plugin. Here is the printout for Hie.

I thought it did not, but it seems the Hie plugin does in fact work despite the errors unlike the other one.

[jneira]

Yeah, it only clutters the log. It is a stack specific bug and hie triggers stack executions to configure and get info from the project. See https://github.com/haskell/haskell-ide-engine/issues/1428 for more context and a workaround. I will close as duplicate of #1428 if you dont mind.
