## Describe the issue/error/question

When I use the **Move Binary Data** node to encode binary data to base64 in json I receive an error. The binary files are PDF files and in my test I have 2 records with correct binary files. When I try to convert these into Base64 I received an N8N-error.

## What is the error message (if any)?

ERROR: Unexpected token J in JSON at position 0

Hi @laurens-novyx, I’m sorry to hear that.

From your screenshot it seems you are converting binary data into n8n-compatible JSON data. Does your base64 content consist of valid JSON? If not, could you try disabling the _Set all Data_ option and see if this works?

That works. Thanks!
