The ChatGPT Alpha with Plugins is error prone recently

I’m using the Alpha version of ChatGPT with Plugin beta. Over the past few days, I have found that the gpt-4-plugins model works well without enable any plugins:

However, it frequently goes wrong(the backend conversation API returns 500) when it tries to invoke the plugin:

This suggests that there may be an underlying issue within the plugin layer.

I’m curious to know if anyone else has encountered this same issue?
