JustGui opened a new issue, #27939:
URL: https://github.com/apache/superset/issues/27939
### Bug description
Importing a dataset/chart/dashboard linked to a Trino database with
TRINO_EXPAND_ROWS=True and "Row expansion in schema" activated, returns an
error via the API & Superset interface.
To avoid this error, you need to remove the following lines from the YAML
file before importing:
```
schema_options:
expand_rows: true
```
Superset API shouldn't break when new extras are added to a database as the
database itself isn't altered when we remove existing extras from the YAML file
and import the dataset with this altered schema. It seems like the extra in the
YAML doesn't really matter at the end, so it shouldn't break the API.
Thx!
### How to reproduce the bug
1. Add the feature flag "TRINO_EXPAND_ROWS": True
2. Enable "Row expansion in schema" on a Trino database
3. Export a dataset as a zip using this database via the interface
4. Import again this dataset (the same zip file)
5. After validating, instead of proposing to overwrite your dataset, it will
return an error
