Hi,
I solved the problem upgrading all the python components, with the following command:
pip install --upgrade requests vconnector vpoller pyvmomi
and then restarted the workers.
I think that upgrading pyvmomi is enough to make vpoller work again, but decided to upgrade the 4 components just to make sure.
