[GitHub] [superset] gl opened a new issue #17430: superset export_dashboards not working (1.3.2 or master) - JSON TypeError
gl opened a new issue #17430:
URL: https://github.com/apache/superset/issues/17430
Hello,
I can't seem to be able to export all my dashboards, whether using 1.3.2 nor current master. It is broken in cli (see below), and from the GUI, a bulk export just hangs indefinitely.
Note that the database is sqlite and was upgraded just before from a very old version to the most recent one.
This is 1.3.2 output:
superset@f6c836281487:/app$ superset export_dashboards -f /tmp/d.json

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

DB:
`position_json` and `json_metadata` is empty which is breaking the export dashboard api flow.

Hi @gl you may want to try the new import/export feature which is currently behind a feature flag, as this old version is soon to be deprecated. The flag is `VERSIONED_EXPORT=True`
