Thanks <@701030996430159872>, I brought the message here because it's related to lambda.

So after debugging the function in the SDK that doe the progress checking I figured out that one of the reasons it crashes is that in the response internally, sometimes the "chunks" come back as a float but the type of "chunks" in RenderProgress struct type is an int so it can't convert it and it errors out.

I just ignored it when I get that error and recheck again and that worked for me
