Abdulrehman-PIAIC80387 opened a new issue, #40165:
URL: https://github.com/apache/superset/issues/40165
### Bug description
When Superset is configured with the Czech locale (`BABEL_DEFAULT_LOCALE =
"cs"`), every SQL Lab query — including `SELECT 1` — fails with:
```
SupersetErrorsException: [SupersetError(message="'statement_num'", ...)]
```
This is the same bug pattern as #39566 (French), which was fixed by #38494.
The original fix corrected French (and several other languages) but the Czech
translation was missed.
### Root cause
`superset/sql_lab.py:494` calls:
```python
msg = __(
"Running block %(block_num)s out of %(block_count)s",
block_num=i + 1,
block_count=block_count,
)
```
In `superset/translations/cs/LC_MESSAGES/messages.po` (line 10406), the
Czech translation uses the wrong placeholder names:
```
msgid "Running block %(block_num)s out of %(block_count)s"
msgstr "Spouští se příkaz %(statement_num)s z %(statement_count)s"
```
`%(statement_num)s` / `%(statement_count)s` are not passed to `__()`, so
Python's `%`-formatting raises `KeyError('statement_num')`, which propagates as
`SupersetErrorsException` and breaks every SQL Lab query.
### Steps to reproduce
1. Set `BABEL_DEFAULT_LOCALE = "cs"` in `superset_config.py`
2. Restart Superset
3. Open SQL Lab and run any query (e.g. `SELECT 1`)
4. Query fails with `'statement_num'`
### Expected behavior
Queries execute normally regardless of locale.
### Fix
Correct the Czech translation in
`superset/translations/cs/LC_MESSAGES/messages.po`:
```
msgstr "Spouští se příkaz %(block_num)s z %(block_count)s"
```
### Superset version
master / latest-dev (bug present since at least 6.0.0)
