@sdetweil
Thanks a lot. I works now!

@bugsounet
node version: v17.3.0
npm version: 8.3.0

So obviously not the correct version :-( Do you know how I can change the versions?

@bugsounet I followed your instructions but the rebuilding step failed with the following message:

MagicMirror Building module: epoll, Completed: 0gyp: name ‘openssl_fips’ is not defined while evaluating condition ‘openssl_fips != “”’ in binding.gyp while trying to load binding.gyp
✖ MagicMirror Rebuild Failed

Do you know what the problem is? Thanks!
