alicloud oss error

It seems that from certain version of tensorflow_io, this storage type can not be accessed. Below are my tests:

0.19.x Not working
0.17.1 Not working, tf==2.4.2
0.17.0 Not working tf==2.4.0
0.16.0 works tf==2.3.3
0.13.0 works
0.8.1 works

Just have a glimpse of the code, it seems no changes have taken place. Maybe the underline implementation of tensorflow or build is not compatible?
