HI there @yeftanma,

Have you tried with

{
  name: storageQuery.data.name,
  data: storageQuery.data.base64Data
}

You may want to double-check:

  • If Epigeon expects multipart form-data, you may need to switch the body type from binary to form-data and attach the decoded data with the correct content-type header.
  • If the API directly accepts binary stream, ensure the Content-Type header matches (text/csv or application/octet-stream) and send only the raw binary decoded from base64.

Hope this helps!

Epigeon directly accepts binary stream text/csv. Anyway, I've tried with your suggestion and it did not work. It said error expected type object but provided value is string.

Hey @yeftanma,

So the linting error may be a bug. However I just remembed also that within API blocks we need to use curly brackets, so try changing it to

{
name: {{ storageQuery.data.name }},
data: {{ storageQuery.data.base64Data }}
}

Try running it even if you see that error.

Working fine. Thanks a lot @MiguelOrtiz!
