Yep, I can confirm I am getting this error. @obany I think some of the updates made on the https://github.com/iotaledger/explorer has brought this error when it comes to docker.

This was due to the stricter typing of Errors in TypeScript 4.4, a fix has been pushed to the Explorer repo, so it should work now.

@Galman21 you can try test it now and see if it works. It works on my side.
