[Bug] fetch not a function in Discord/Google.stopFlow

[dudeisbrendan03]

Describe the bug 0.1.43 - this.libs.fetch is not a function

Stack:

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason:
TypeError: this.libs.fetch(...).this is not a function
