Hello @Nestify_Online ,
That error usually means n8n is receiving a text string where it expects a JSON object, or there is a slight syntax error in the mapping.
To pinpoint exactly where the format is breaking, could you share a screenshot of the Output from your Code in JavaScript node?
Seeing exactly what data structure is being passed to the HTTP node (specifically if the output looks like a green object or a raw text string) will help us solve this instantly.
Hi @Nestify_Online Welcome!
With the error i can suppose you are not providing the right syntax for the HTTP JSON request, please consider sharing your workflow JSON and error insights.
