The string is neither empty not NULL , can you please give a try with the below syntax and check if it works.

${record:value('/TYPE_1099')?record:value('/TYPE_1099'):NULL}

In this case there is no value for TYPE_1099 ,so that’s reason its throwing error. 

I noticed you are trying to assign NULL value to the string , kindly provide me the pipeline or test file ,so i can check and help you on the same.

Thanks & Regards

i  followed you expression but it  shows  error 
expression used =${record:value('/TYPE_1099')?record:value('/TYPE_1099'):NULL}}

out-put shows excess brackets as a string ,so i reconfigured the expression to remove one brackets like expression used =${record:value('/TYPE_1099')?record:value('/TYPE_1099'):NULL}
again same error 
 

@lakshmi_narayanan_t

My bad there was type in the syntax , can you try with below and check if it helps.

${record:value('/TYPE_1099')?NULL:record:value('/TYPE_1099')}

again same issue
 

There is No change in field values.
 

@lakshmi_narayanan_t

Kindly try with below code snippet and let me know if it helps. I also attached the pipeline for your reference.

Kindly use it in expression evaluator

${str:length(record:value('/VENDOR_NAME_ALT')) != 0 ? record:value('/VENDOR_NAME_ALT') : 'null'}


or 

${record:value('/VENDOR_NAME_ALT')? record:value('/VENDOR_NAME_ALT') : 'null'}
