GitHub "Create a file" node: "content is not valid Base64" error when uploading binary file from HTTP Request node

[Naacal]

I am experiencing an issue when trying to upload a PNG file to GitHub using the “Create a file” node in n8n (version 1.112.6). My workflow is as follows:

1. 2x HTTP Request nodes

   • Downloads a PNG file from a URL

   • “Response Format” is set to “File”

   • “Put Output in Field” is set to data

   • The binary data is valid (I can download and open the file from the node output)

2. GitHub node (“Create a file”)

   • “Binary Property Name” is set to data (matches the HTTP Request node output)

   • The node is directly connected to the HTTP Request node

Despite this setup, I receive the following error in the GitHub node:
Your request is invalid or could not be processed by the service: content is not valid Base64

Troubleshooting steps already taken:

• Verified the binary property name matches (data)

• Confirmed the binary data is valid and the file is not empty or corrupted

• File size is well below GitHub’s API limit

• Tried re-executing the nodes

Request:
Is this a known issue with the GitHub node in n8n 1.112.6? Are there any workarounds or fixes to ensure the binary data is properly encoded and accepted by the GitHub API?

Hi @Naacal

Could you please attach an example of the image you’re trying to upload?
I tested it with an image on my own, and it worked as expected..
