Can I just check how do I turn data into a buffer/file stream that can be used in the ssh2SftpClient plugin?
I tried to use btoa but I get an error saying
[info] unhandledRejection Error: put: Bad path: dGVzdGluZw== not exist
Hey Ernest! Sorry for the delay here. I wanted to sync with my team before getting back to you to make sure I was understanding correctly. To clarify, you're looking for the syntax to convert a binary string to buffer?
Since btoa converts to a base64 string, I think you can convert the output from that to a buffer with ArrayBuffer, though that might not be exactly what you're looking for. Let me know! 
Hi Victoria,
Managed to get this working, ended up using Buffer.from(str) to get the buffer for upload.
It was just confusing because it complains that Buffer is not defined.
Hope this helps others!
Amazing! So glad to hear it + will look into the confusing Buffer linting.
