@Bikram  any suggestion?

@akanshajain6793 

Kindly provide me the sample data ,so i can try to get the number of parameters in it.

@Bikram  above is the data i have

first request -

request_param:

0:

   a : “11”

   b: “12”

   c: “12”

   d: “12”

second request -

request_param:

0:

   a : “11”

   b: “12”

   c: “12”

@akanshajain6793 

If the request_param  is a map , can you please try to get the size of the map using size(request_param) in expression evaluator.

If you can provide me the actual parameter ,so i can try to help you.

The above parameters seems like dummy one but i want the json data which will help me to reproduce the issue.

You also can try to get the size of the map in jython evaluator and proceed further.

Thanks & Regards

Please flatten the nested json and use the below code to get the parameter count in your pipeline.

#newRecord = sdcFunctions.createRecord('header')

val = ''
## Sample Jython code
for record in sdc.records:
  try:
    count = 0
    for key in record.value:
      count += 1
      record.value = {"txt":count}
      
    sdc.output.write(record) 
    # Write record to processor output
    
    

  except Exception as e:
    # Send record to error
    sdc.error.write(record, str(e))
    sdc.output.write(recor

You can use Expression Evaluator.

${ length( record:value('/f1'))}

If field f1 holds 4 values then the above expression will return 4.

as @Bikram  suggested, use size() function of you want to get the number of attributes in a MAP

or use length if you want to count number of items in a LIST
