Hey! I just finished "The FIRST Ai Agent To Make Money On Autopilot (No-Code tutorial)". Everything works besides the last step. It gives me an error saying: Problem in node ‘Instagram‘ JSON parameter needs to be valid JSON I did copy the exact json format from here, so i am not sure why it's not working. This is my json file { "post": { "accountId": "{{ $json.instagram }}", "target": { "targetType": "instagram" }, "content": { "text": "{{ $json.captions }}", "platform": "instagram", "mediaUrls": [ "{{ $json.url }}" ] } } } Any help would be appreciated. Thanks, Sebastian
