I have a binary pdf as a Uint8Array that I want to convert to base64 to eventually store in Netsuite as a file. Has anyone found a (somewhat) working way of doing that? I've tried many different variations of converting it. One of them using this library. But it gave me this nice error from NS.

{
   type: "error.SuiteScriptError",
   name: "",
   message: "com.netsuite.suitescript.scriptobject.ScriptNullObjectAdapter@1e96d033"
}
