The number of parameter values set or registered does not match the number of parameters., Reason: Script failed with the following error: The number of parameter values set or registered does not match the number of parameters

When I try to call a SP in DB2 using script snap with python language which has total 7 parameters out of it 5 are input and 2 are output parameters. I am getting below error even though I am registering 2 output parameters.

Error message:
The number of parameter values set or registered does not match the number of parameters., Reason: Script failed with the following error: The number of parameter values set or registered does not match the number of parameters.

Below is the code which I am using:

Import the interface required by the Script snap.

from com.snaplogic.scripting.language import ScriptHook

import java.util
import java.sql.DriverManager
import java.sql.Connection
import java.sql.Types
import java.sql.DatabaseMetaData
import sys

class TransformScript(ScriptHook):
def init(self, input, output, error, log):
self.input = input
self.output = output
self.error = error
self.log = log

# The "execute()" method is called once when the pipeline is started
# and allowed to process its inputs or just send data to its outputs.
def execute(self):
   # self.log.info("Executing Transform script")
    while self.input.hasNext():
        try:
            # Read the next input document, store it in a new dictionary, and write this as an output document.
            inDoc = self.input.next()
            
            conDB2 = java.sql.DriverManager.getConnection()
            db2Query = conDB2.prepareCall(CALL SP('"+inDoc['input1']+"','"+inDoc['input2']+"','"+inDoc['input3']+"','"+inDoc['input4']+"','"+inDoc['input5']+"',?,?) 
             

            self.output.write("SP OUT")
            db2Query.registerOutParameter(1, java.sql.Types.INTEGER)
            self.output.write("OUT 1")
            db2Query.registerOutParameter(2, java.sql.Types.CHAR) 
            self.output.write("OUT 2")
            
            
            isRanSuccessfully = db2Query.execute()
            returnCode = db2Query.getString(1)
            otherMIS = db2Query.getString(2)
            outDoc = {
                'original' : inDoc['Stored_Proc']
                #"CALL SP('"+inDoc['input1']+"','"+inDoc['input2']+"','"+inDoc['input3']+"','"+inDoc['input4']+"','"+inDoc['input5']+"',?,?)"

            }
            
            self.output.write(inDoc, outDoc)
        except Exception as e:
            errDoc = {
                'error' : str(e)
            }
            self.log.error("Error in python script")
            self.error.write(errDoc)

    self.log.info("Script executed")

# The "cleanup()" method is called after the snap has exited the execute() method
def cleanup(self):
    self.log.info("Cleaning up")

The Script Snap will look for a ScriptHook object in the “hook”

variable. The snap will then call the hook’s “execute” method.

hook = TransformScript(input, output, error, log)

I have the hook object at the end of script. it may not visible in my post.

Are you missing double quotes in your prepareCall? That is, "CALL SP('" and trailing single quote should be closed "'".
