N8n - Google Cloud Vision API (OCR) + Email Trigger Imap

[GregNCW]

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.
   
   
   
   
   
   
   
   
   
   
   

I’m attaching screenshots showing how it all looks.

hello @GregNCW

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

You forgot to remove "= before double brackets {{
