Cannot read property 'getGlobalStorage' of undefined

[StErMi]

I'm reporting the issue also here so people that will come across will find an open ticket.

I've setup the example, run npm run dev and the second (and all the next) time I call the API I get this error:

offline: GET /book (λ: book)

Note: The only different thing from the example is that I'm using @mikro-orm/[email protected] instead of the mysql package.

what could be the issue?
