Do someone know what is hapenning here?

the base64 have 3mb size. Mybe this is the cause of the error. How do I do in this case to convert My base64 to file? Im trying to convert it so I can send it to supabase blob and get only the URL link, but even to convert the file im getting an error.

I got the solution from it by myself doing a Code node with the script below:

// Access the first input item
const item = $input.first();

// Retrieve the Base64 string from the JSON data
const base64String = item.json.image

// Remove any data URL prefix if present
const cleanedBase64 = base64String.replace(/^data:.*;base64,/, '');

// Decode the Base64 string into a Buffer
const buffer = Buffer.from(cleanedBase64, 'base64');

// Prepare the binary data using n8n's helper function
const binaryData = await this.helpers.prepareBinaryData(buffer, 'output.jpg'); // Replace 'output.pdf' with your desired filename

// Return the binary data
return {
  json: {},
  binary: {
    data: binaryData
  }
};
