Anaconda Error – module ‘brotli’ has no attribute ‘error’

I solved this issue by commenting lines 376 & 377 in the file

C:\ProgramData\Anaconda3\Lib\site-packages\urllib3\response.py

and then install brotli library by running either

pip install brotli

or

conda install brotli

After successful installation, uncomment above lines.
Do whatever you want now. Error should not come.
