Errors on API calling when running on the server

I am running my code on cloudlab, and it keeps sending me errors like the one shown below.

This error jumps out several times today. I have no idea on this AWS WAF error, and I never met this kind of error in my previous running. Can someone tell me how to avoid that?

We are looking into this now - assuming you were using our API, we’ve made some adjustments for now to prevent this error while we dig into the cause.
