JayjeetAtGithub opened a new issue, #7345:
URL: https://github.com/apache/arrow-datafusion/issues/7345
### Describe the bug
### Describe the bug
On running the query below on the Clickbench multi file dataset,
```sql
SELECT REGEXP_REPLACE("Referer", '^https?://(?:www.)?([^/]+)/.*$', '1') AS
k, AVG(length("Referer")) AS l, COUNT(*) AS c, MIN("Referer") FROM hits WHERE
"Referer" <> '' GROUP BY k HAVING COUNT(*) > 100000 ORDER BY l DESC LIMIT 25;
```
we get this error,
```bash
Internal error: The "regex_replace" function can only accept strings.. This
was likely caused by a bug in DataFusion's code and we would welcome that you
file an bug report in our issue tracker
```
### To Reproduce
Download the data using,
```bash
./benchmarks/bench.sh data clickbench_partitioned
```
A `hits_multi` directory with the parquet files will be created.
Execute the above queries,
```bash
datafusion-cli -c "CREATE EXTERNAL TABLE hits STORED AS PARQUET LOCATION
'hits_multi';" "{query}"
```
### Expected behavior
The queries should run successfully without erroring.
### Additional context
Datafusion 29.0.0
