@CptHolzschnauz what Node version are you using?

[CptHolzschnauz]

Welcome to Node.js v12.22.9.

[marco-c]

Node 12 is no longer supported. The minimum supported version is Node 16.

[CptHolzschnauz]

Sorry for the hassle. I didn't get that's a version 16. With ubuntu 12 is somehow standard. My fault. Thank you anyway.
