lrioo opened a new issue #9904:
URL: https://github.com/apache/incubator-superset/issues/9904
when I run a query with the clickhouse database, this error appeared.
Has anyone else resolved it?
### Expected results
query finish and then display the result
#### How to reproduce the bug
1. Add clickhouse database and tables
2. Run a query with a 'string' type filed in GROUP BY
3. Error("clickhouse error: 'str' object has no attribute 'to_python'")
appeared
### Environment
- superset version: 0.30.1
- python version: 3.6.9
- sqlalchemy-clickhouse version: 0.1.5.post0
- infi.clickhouse_orm version: 1.4.0
### Checklist
I run superset in the Intranet, so... no access to provide the python
stacktraces
- [ ] 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
I'd tried to downgrade the version of sqlalchemy-clickhouse &
infi.clickhouse_orm, just like mentioned in the issues
[#5345]<https://github.com/apache/incubator-superset/issues/5345>.
eg:
sqlalchemy-clickhouse==0.1.3.post0 & infi.clickhouse_orm==1.0.0
sqlalchemy-clickhouse==0.1.0.post0 & infi.clickhouse_orm==0.9.8/0.7.1
But it's not work, and always with another error.
