thoniTUB opened a new issue, #61490:
URL: https://github.com/apache/airflow/issues/61490
### Apache Airflow version
3.1.7
### If "Other Airflow 3 version" selected, which one?
_No response_
### What happened?
I strumbled on this inconsistency:
#### Not Working: Create Variable with CLI Import
I cannot import this variable from a file using the cli command `airflow
variables import variables.json`:
```yaml
# variables.json
{
"var1": [
{
"foo": "bar"
},
{
"bar": "foo"
}
]
}
```
It fails with the message:
> The "variables.json" file contains multiple values for keys: ['var1']
#### Working: Create Variable using the UI
I can however create this variable in the UI.
Then I can use `airflow variables export variables.json` to dump the very
same JSON as above, which cannot be imported again.
### What you think should happen instead?
[The code
here](https://github.com/apache/airflow/blob/8f3ae04f89e4679c02b4a2500557cf46863af854/airflow-core/src/airflow/secrets/local_filesystem.py#L247)
blocks this import of a list value with more than 1 item.
However, it does not explain why a list with multiple elements is not
allowed here.
### How to reproduce

RHEL 9
### Versions of Apache Airflow Providers
