General information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Ubuntu 20.04.4 LTS (Focal Fossa)
• ElasticHQ Version: 3.5.12
• Elasticsearch Version: 8.1.0
• Python version (ignore is using docker image): Python 3.8.10
• Browser Vendor and Version (if applicable): Google Chrome Version 99.0.4844.83 (Official Build) (x86_64)

Issue Description

I downloaded the ElasticHQ 3.5.12 and installed the requirements.txt. First I got this issue #515 I followed the instruction mentioned over there. After this I got this issue ImportError: cannot import name '_endpoint_from_view_func' from 'flask.helpers' (/usr/local/lib/python3.8/dist-packages/flask/helpers.py). I fixed it following this link and installed Flask-RESTful==0.3.9. After this I ran this command python3 application.py and visited my browser to connect with es cluster then it showed the below error on the terminal.
