Usiel opened a new issue, #20679:
URL: https://github.com/apache/superset/issues/20679
Explore UI errors out when a time-series based chart is selected and one of
the non-time dimensions has an empty value `''`.
#### How to reproduce the bug
1. Load the `birth_names` example dataset
2. Add a calculated column called "empty" with the following expression:
`CASE WHEN gender = 'girl' THEN 'Girl' ELSE '' END`
3. Create a chart based on the `birth_names`
4. Select any time-series viz type
5. Group by the new calculated dimension
6. Update Chart
### Expected results
Results tab loads the results grouped by time with the calculated dimension
as columns.
### Actual results
Page goes blank with the following error:
```
