LGTM, thank you for quickly fixing this issue 🙂
Could the test failure be because the blockchain isn't deployed yet?

Yes, it needs release of the server-side change: ainblockchain/ain-blockchain#1261

@platfowner I encountered the following error when building locally.

I saw this similar error, and adjusted the version of @types/ws to 8.5.3 resolved the issue.
Could you please downgrade the version to 8.5.3?
