This issue is present even in 1.3.0 and has been taken forward to 1.4.0 as well. Let me add more context on this. 1. Login to superset and create a new chart. 2. Click `Save`, and give some name and create a new dashboard, and click `Save and Go to Dashboard` 3. Now go to Dashboard list and locate the one created and in actions, click `Export` 4. The UI hangs forever with loading icon. Also added the video for the above steps https://user-images.githubusercontent.com/29149291/145955274-c0efbf0c-2480-452c-830c-c43db280ed2e.mp4 Logs: ``` 2021-12-14 07:14:25,878:ERROR:root:the JSON object must be str, bytes or bytearray, not NoneType Traceback (most recent call last): File "/usr/local/lib/python3.8/site-packages/flask_appbuilder/api/__init__.py", line 85, in wraps return f(self, *args, **kwargs) File "/app/superset/views/base_api.py", line 85, in wraps raise ex File "/app/superset/views/base_api.py", line 82, in wraps duration, response = time_function(f, self, *args, **kwargs) File "/app/superset/utils/core.py", line 1464, in time_function response = func(*args, **kwargs) File "/usr/local/lib/python3.8/site-packages/flask_appbuilder/api/__init__.py", line 155, in wraps return f(self, *args, **kwargs) File "/app/superset/utils/log.py", line 242, in wrapper value = f(*args, **kwargs) File "/app/superset/dashboards/api.py", line 743, in export export = Dashboard.export_dashboards(ids) File "/app/superset/models/dashboard.py", line 385, in export_dashboards json_metadata = json.loads(dashboard.json_metadata) File "/usr/local/lib/python3.8/json/__init__.py", line 341, in loads raise TypeError(f'the JSON object must be str, bytes or bytearray, ' TypeError: the JSON object must be str, bytes or bytearray, not NoneType ``` DB:  `position_json` and `json_metadata` is empty which is breaking the export dashboard api flow. -- This is an automated message from the Apache Git Service.
