shawnzhu opened a new issue #15258: URL: https://github.com/apache/superset/issues/15258
I've following the guide [here}(https://superset.apache.org/docs/installation/cache) to setup Redis as data cache with superset from master branch. ### Expected results Superset should work as it was without data cache configuration. ### Actual results None of the chart works in any dashboards. While if clicking _Force Refresh_ option of a chart then it works again but still doesn't work when refreshing the whole dashboard. #### Screenshots  #### How to reproduce the bug 1. Go to any dashboard 2. See error message `'Flask' object has no attribute 'get'` ### Environment (please complete the following information): - superset version: `Version: 0.999.0dev` - python version: `3.7.9` the stacktrace from webserver log: ``` 10.0.2.100 - - [18/Jun/2021:13:42:00 +0000] "POST /api/v1/chart/data?form_data=%7B%22slice_id%22%3A62%7D&dashboard_id=2 HTTP/1.1" 500 236 "http://localhost:8088/superset/dashboard/births/"; "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.150 Safari/537.36" 'Flask' object has no attribute 'get' Traceback (most recent call last): File "/app/superset/views/base.py", line 204, in wraps return f(self, *args, **kwargs) File "/app/superset/utils/log.py", line 228, in wrapper value = f(*args, **kwargs) File "/app/superset/utils/cache.py", line 159, in wrapper return f(*args, **kwargs) File "/app/superset/views/utils.py", line 470, in wrapper return f(*args, **kwargs) File "/app/superset/views/core.py", line 634, in explore_json return self.generate_json(viz_obj, response_type) File "/app/superset/views/core.py", line 454, in generate_json payload = viz_obj.get_payload() File "/app/superset/viz.py", line 450, in get_payload payload = self.get_df_payload(query_obj) File "/app/superset/viz.py", line 500, in get_df_payload cache_value = cache_manager.data_cache.get(cache_key) File "/usr/local/lib/python3.7/site-packages/flask_caching/__init__.py", line 248, in get return self.cache.get(*args, **kwargs) File "/usr/local/lib/python3.7/site-packages/flask_caching/backends/rediscache.py", line 114, in get self._read_clients.get(self._get_prefix() + key) AttributeError: 'Flask' object has no attribute 'get' ``` ### Checklist Make sure to follow these steps before submitting your issue - thank you! - [x] I have checked the superset logs for python stacktraces and included it here as text if there are any. - [x] I have reproduced the issue with at least the latest released version of superset. - [x] I have checked the issue tracker for the same issue and I haven't found one similar. ### Additional context Add any other context about the problem here. -- This is an automated message from the Apache Git Service.
