@vcolin7, just did some tests.

Before applying the latest changes, the error only happened to the sync client.

After applying the latest changes, both sync and async clients can work now.

So I am going to close this issue. Thanks for the help.

@saragluna Xiaolu Dai FTE, @stliu Strong Liu FTE We just merged this fix, would you mind checking if this is still happening for you?

@vcolin7, thanks. Will try it now.
