Describe the problem/error/question
I have a workflow to process some nested JSON data, in the MSSQL node I tried to map the value of the SET node, but its shows “undefined”.
What is the error message (if any)?
Please share your workflow
(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)
Share the output returned by the last node

Hi @Meghna_jose, I am sorry you are having trouble. I won’t be able to run this workflow myself as I don’t have access to your credentials, but I suspect you are affected by the issue @fxholl has reported over here.
Can you confirm if this is just a problem with the expression preview or if this actually breaks your workflow?
