Reference to a name which is not a local, a builtin, or an external INLINABLE function #79

Trying to build a very simple minting policy for an NFT I get the following error; this happens also for the code of Week05.NFT module; what can be a cause?

Hi, @HarmonicPool! I'm sure by now you know that the problem most likely was that you were trying to compile a function that didn't have the INLINABLE pragma (either created by you or imported from somewhere else). Closing the issue. Sorry no one answered earlier.
