Hello dear friends, Thank you for reading this, let me get into it: I have a workflow that takes a form (onboarding form) and creates a market research and creative brief out of it. I do this with HTTPS and DeepSeek. Using deepseek means I have to use JSON to add the prompt (as I know of) and I don't know nothing about JSON. usually the prompting goes well, If I go from the form to deepseek right away. But if I have another node in the middle (for example: form - drive - https) and I add info to the prompt from the form it says an error (JSON parameter needs to be valid JSON) And right now, I have the same problem, as I added to the end of the workflow an other DeepSeek node (https) where it takes the market research document and writes an Ad Hook from it. The point is the "Get Document" is before the deepseek node, and it runs smoothly until I add any expression or data from previous nodes. "role": "user", "content": "Market Research: {{ $json.content }}" What is the JSON problem and how can I reliable always reference data without JSON error? I would actually pay for someone's help
