Omega359 opened a new issue, #13347:
URL: https://github.com/apache/datafusion/issues/13347
### Describe the bug
```
query T
select COALESCE(arrow_cast(null, 'Utf8'), arrow_cast('t', 'Utf8View'));
----
t
```
External error: query failed: DataFusion error: Error during planning:
Execution error: User-defined coercion failed with Execution("Fail to find the
coerced type, errors: Some(Execution(\"Expect to get struct but got Utf8\"))")
No function matches the given name and argument types 'coalesce(Utf8,
Utf8View)'. You might need to add explicit type casts.
Candidate functions:
coalesce(UserDefined)
### To Reproduce
See bug description. Test passes if all values are Utf8
### Expected behavior
The test should pass
### Additional context
Seeing this after upgrading to latest HEAD as of Nov 10 2024.
