ERROR: JSON parameter need to be an valid JSON dinamic parameter

[Pedro_Malaquias]

Hello everyone, everything good?
I’m trying to make a “birthday” flow, everything was working until I started using the variables in the last step, since then it started giving the following error: “ERROR: JSON parameter needs to be a valid JSON”, but the request worked the first time and then I just make an error, can someone help me please, I’ve already reviewed the JSON but without success.

Copy the workflow with ctrl+a → ctrl+c

Then hit here on the </> button and past the content with ctrl+v

Where are you receiving the body and description values for the first HTTP node? But it won;t cause issues anyway.

Replace the payload of the second HTTP node’s body with that one:

{
    "cards": [
      {
        "header": {
          "title": "Hoje temos um aniversariante!"
        },
        "sections": [
          {
            "widgets": [
              {
                "textParagraph": {
                  "text": {{ JSON.stringify($json.choices[0].message.content) }}
                }
              },
              {
                "image": {
                  "imageUrl": {{ JSON.stringify($('inicio').item.json.image) }},
                  "altText": "Nature"
                }
              }
            ]
          }
        ]
      }
    ]
  }

          }
        ]
      }
    ]
  }

can you explain better?
The first data I force into a json at the “beginning”

[Pedro_Malaquias]

It worked, but now regardless of the link I put, the image doesn’t appear

[barn4k]

maybe AI can’t access the link?

[Pedro_Malaquias]

But the image doesn’t come from AI, it comes from Google Drive, and even if it did, I tried with image links directly from Google and I wasn’t successful

[Pedro_Malaquias]

The problem with the privacy of the images has already been resolved, thank you for your collaboration!
