problems with bulk user update

[jsiragusa]

I'm having issues making a bulk user update. I'm following the docs here https://getstarted.sailthru.com/developers/api/job/#update-json-example, but when I make the call to apiPost it throws an error:

17 Jan 09:11:29 - sailthru-client - https://api.sailthru.com/job
17 Jan 09:11:29 - sailthru-client - MultiPart Request
17 Jan 09:11:29 - sailthru-client - JSON Payload: {"api_key":"XXXXXX","format":"json","json":"{\"job\":\"update\"}","sig":"XXXXXXX","file":{"path":"./userdata.txt","filename":"userdata.txt","fileSize":0,"encoding":"binary","contentType":"application/octet-stream"}}
internal/fs/utils.js:288
    throw err;
    ^

TypeError [ERR_INVALID_ARG_TYPE]: The "buffer" argument must be one of type Buffer or Uint8Array. Received type number
    at Object.read (fs.js:440:3)

    at /Users/jon/dev/patch/sailthru/node_modules/restler/lib/multipartform.js:129:10
    at FSReqWrap.oncomplete (fs.js:139:20)

Here is my relevant code:

const filename = './userdata.txt';
sailthru.enableLogging();
sailthru.apiPostAsync = util.promisify(sailthru.apiPost);
await sailthru.apiPostAsync('job', {'job': 'update', 'file': `${filename}`}, ['file']);

And the contents of userdata.txt (which is in the current directory and readable):

{"id":"user1@example.com","keys":{"extid":"11111"},"fields":{"keys":1},"vars":{"somevar":"abc"}}
{"id":"user2@example.com","keys":{"extid":"22222"},"fields":{"keys":1},"vars":{"somevar":"def"}}
{"id":"user3@example.com","keys":{"extid":"33333"},"fields":{"keys":1},"vars":{"somevar":"ghi"}}

Any ideas? I'm about to dig into the apiPost code, but thought I'd post here first.

This issue was being caused by a dependency that was not updated alongside Node's fs module. This has been updated and should be fixed with the latest update, v3.0.4

Updated to v3.0.4 and can confirm that this is fixed. Thanks!!
