I tried the following and got an error.  What's the issue?

Here is the registered function the agent will call:

def myFunction(col_val1: str, col_val2: str) -> str:
"""
A function that will accept 2 strings from caller and insert into a table.
"""
from pyspark.sql.session import SparkSession
spark = SparkSession.builder.getOrCreate()
spark.sql(f"CALL myCatalog.mySchema.myStoredProcedure('{col_val1}', '{col_val2}');")
return "Data inserted successfully."

Then from Playground, load the Tool to the above function and ask agent to insert data.  Got the below error:
