node@23 - FabricManager unavailable due to initialization error

[t0bst4r]

When upgrading to node 23.4.0 i found the following error when starting my bridge with existing fabrics.

FabricManager unavailable due to initialization error
       at crashedError (/Users/t0bst4r/Projects/t0bst4r/home-assistant-matter-hub/node_modules/@matter/general/src/util/Construction.ts:600:28)
       at handleRejection (/Users/t0bst4r/Projects/t0bst4r/home-assistant-matter-hub/node_modules/@matter/general/src/util/Construction.ts:311:69)

I simply added a try {... } catch (e) { console.log(e); throw e; } in the initializer of the FabricManager and found the following error message:

TypeError: input.codePointAt is not a function

When removing the "fabrics" section from the storage, the bridge booted succesfully without fabrics (of course).

When rolling back to node 22.12.0 it's working with the given storage.

[Apollon77]

Thanks for reporting! It seems that Node.js 23 uses other access methods on the object too and I would assume that the lines here

matter.js/packages/general/src/crypto/Key.ts

Lines 485 to 486 in fcd71a9

	get: () => that[target] !== undefined && Base64.decode(that[target]),
	set: value => (that[target] = value === undefined ? undefined : Base64.encode(value, true)),

need handling if the value is not a string because seems to be that the value was not undefined but also no string on get
