I am not dealing with a file. Just a base64 string that needs to be decoded into a JSON object so I don’t see how the file flow functions can help there.
The Javascript node doesn’t work is it is most likely a cut down version and seems not to have access to the required functions to make the code work as described above.
I’m using JWT as well, but I don’t need to decode them. My node.JS backend is decrypting as needed, mostly in my auth route.
Haven’t done anything with JS inside AG.
