JSON object vs list of strings?

As a proof of concept, I setup a working flow that downloads a CSV file, renames the keys (using a Rename Keys node) so the keys match the table field names that the data will eventually be imported into. Then, using a MySQL node, the workflow successfully imports the data into the MySQL table.

Now I would like to return the entire output of the Rename Keys node as JSON so that the workflow behaves like an API call triggered by a Webhook. No matter what I try, I can only receive the first line of the data from the Rename Keys node instead of the entire JSON data. It seems like the Rename Keys node passes a list of strings instead of the entire JSON payload.

How do I get the entire payload from a Rename Keys node into the body of a Webhook response?

Hi Rickerdo,

I am sorry to hear you’re having trouble but am unfortunately not sure I fully understand the problem. Assuming I have multiple items with a key, the Rename Keys node would change the key across all items, even if they aren’t strings:

Would you be able to share an example of the JSON data you have along with the data you would like to see following the Rename Keys node?
