DataError: Source is not valid JSON Data size: 0 from Google Gemini AI module

How To
1

I have a Make.com scenario where I’m fetching data from a Google Gemini AI module. The AI’s output is a text string that begins with json\n{...}.

I’ve attempted to clean this output using a Text parser module with the Match pattern action (using the pattern \{.*) specifically to extract only the JSON object portion ({...}).

However, when I pass the result from the Text parser to a Parse JSON module, I consistently get a DataError: Source is not valid JSON. Upon inspecting the input of the Parse JSON module, it appears to be receiving the original raw data from the AI module (still prefixed with json\n) or, in some instances, the input log shows Data size: 0 even if a preview of the incorrect string is visible

Hey Philip,

can you share the output bundles themselves along with screenshots of the current module setup? It will be easier to see what you are working with.
