## TL;DR

The VWO docs say getAndUpdateSettingsFile is available in the Node.js SDK from v1.10 onward, but calling vwoSDK.getAndUpdateSettingsFile() throws not a function even on v1.10.

## Steps

1. The VWO docs say getAndUpdateSettingsFile is available in the Node.js SDK from v1.10 onward, but calling vwoSDK.getAndUpdateSettingsFile() throws not a function even on v1.10. The method lives on the client instance, not on the SDK module object.

2. Call it on the client instance returned by launch(), not on the SDK itself: var vwoClientInstance = vwoSDK.launch({ settingsFile: settingsFile }); vwoClientInstance.getAndUpdateSettingsFile().then(...). That is the documented usage.

## When to use

You are seeing this: The method lives on the client instance, not on the SDK module object. Use this skill when you run into "vwoSDK.getAndUpdateSettingsFile is not a function".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

Versions mentioned in the source: v1.10. If you are on something much newer or older, the details may have shifted.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
