Problem
@Andrea_Nerla: Hi folks, I’m receiving this error every time I try to run a Prefect script. For context I’m trying to receive Slack’s status notifications so I added the SLACK_WEBHOOK_URL in the config.toml and I’ve also opened prefect’s _init_.py out of curiosity. I don’t think I changed anything in it but I might have misclicked something.

@Kevin_Kho: Are you using flow.run() or is this with an agent?
@Andrea_Nerla: Right now I restarted the system and I’m trying to run prefect agent local start , which gives me this error. But before of it I was having the same error with a flow.run()
@Kevin_Kho: Can you do pip show python-box in your terminal and show me the output?
@Andrea_Nerla:
@Kevin_Kho: And for pip show prefect?
@Andrea_Nerla:
Solution
@Kevin_Kho: I am on the same but can’t replicate. I would honestly just try re-installing prefect
@Andrea_Nerla: It did resolve the error, thanks.
