File handling

Hi!
I would like to upload a freshly created json file to github. i had issues earlier with references pointing to files.
I was hardly able to get the content of the file and ‘inject’ it from an earlier node (before file creation)

However its far form an elegant solution, i would like to upload the json file created from the convert to file node.

How to refer to the file? i tried with the following:
data
persona_company
{{ $persona_company }}

i also got error messages like the object can not be applied.

are there any best practices to call the file i want to upload in this case, or in general?

and always encountered error messages like this:

I wouldn’t use Github for this but prefer S3. You can get cheap S3 storage anywhere for $5-7 per TB per month. Object storage is so much better.

thank you, but I’m struggling to refer to any files, regardless where i want to upload, and did not figure out yet how to handle files in n8n.
(a webpage would load the data from the json in this case, but i had the same issue when I tried to upload to Google Drive, or any similar move)

so the question would be the same for all cases, how to refer to the json file created in the binary node. i would really appreciate a help
