Hi!
I have a problem in n8n with sending attachments in an HTTP Request for the Cloud Vision API.

  1. The first node is an Email Trigger IMAP where I fetch the attachments.
  2. The second node is a Code node where I convert the attachments to binary.
  3. The third node is an HTTP Request for the Cloud Vision API where I set the body with the attachments.

hello @GregNCW

Replace the content value with {{ JSON.stringify($json.base64Attachment) }} (and no quotes around)
