This build was successfull for 2 day ago. Currently, this build was failed.
What should I do for successful build?

Hrm... This is a problem introduced in #8865 when using Python2.7 --which is deprecated. We may need to do some extra work on the Python2.7 case.

Since we are already talking about this, are you using Python2.7 for a particular reason? Note that Python 2.7 reached the end of its life on January 1st, 2020. I really recommend you to upgrade to Python 3 if that's possible. Otherwise, you will keep hitting issues like this one.

I have change Python version from 2 to 3 in my project, and it works. But it still looks as incorrect behavior for Python 2.7.

We solved this problem and we plan to deploy it later today.
