   In Python you cannot call `compute.min_max` for the JSON type. 
   
   Reproduce the error with:
   
   ```python
   import pyarrow as pa
   import pyarrow.compute as pc
   
   table = pa.Table.from_arrays(
       [
           ["{}", "[1,2,3]"],
       ],
       schema=pa.schema(
           [
               pa.field("json_data", pa.json_(pa.string())),
           ],
       ),
   )
   
   bounds = pc.min_max(table["json_data"])
   ```
