Got the same error

kclowes commented 3 months ago

I'm not able to replicate. I suspect it's an environment issue. Try in a fresh environment, and if you're still seeing this issue, reopen with more info.

Another environment with web3 version 6.9.0, worked with no problems, so for the above environment we also changed the version to 6.9.0 from 6.20.0, and the django server runs normally. It seems that everything starts with this import of web3 that triggers the asyncio.Event() call at the persistent.py file, that isn't probably part of the code at versions older than 6.10.0 (based also on the release notes).
