Subprotocol error when creating connection with ws@8.0.0

See original GitHub issue

The 8.0.0 version of ws introduced some breaking changes around protocols. Attempting to create a connection with this version yields the following error.

Rolling back to 7.5.3 makes the issue go away.

Hello, everyone! Are there any good news on this issue? 😃

DamiTomacommented, May 17, 2022

@oberstet I would suggest to also update the README, as it can be misleading for newbies. Initially I thought it supported up to version 2, we can probably get rid of the comment for Node V4.5.0 (I guess no one has been using that for years).
