clojurians-org opened a new issue, #2260:
URL: https://github.com/apache/arrow-datafusion/issues/2260
**Describe the bug**
```
index out of bounds: the len is 0 but the index is 0
```
**To Reproduce**
``` rust
context.register_udf(create_udf(
"database", vec![], Arc::new(DataType::Utf8),
Volatility::Volatile,
Arc::new(move |args: &[ColumnarValue]| {
let len: usize = match &args[0] {
ColumnarValue::Array(array) => array.len(),
_ => {
return Err(DataFusionError::Internal(
"Expect random function to take no
param".to_string(),
))
}
};
let values = std::iter::repeat_with(||
"default").take(len) ;
let array = StringArray::from_iter_values(values) ;
Ok(ColumnarValue::Array(Arc::new(array)))
})
)) ;
```
**Expected behavior**
**Additional context**
```
arrow = "9.0"
datafusion = "7.0"
```
