TypeError: Cannot read property 'Buffer' of undefined

[sitch]

When transit-js gets imported into jest I get the following error:

    TypeError: Cannot read property 'Buffer' of undefined

      1 | import React from "react"
    > 2 | import { Builder, Query, Utils } from "react-awesome-query-builder"
        | ^
      3 | 
      4 | import configFn from "./config"
      5 | import "./styles.less"

The specific function failing is:

com.cognitect.transit.handlers.defaultHandlers = function(a) {
  a.set(null, new com.cognitect.transit.handlers.NilHandler);
  a.set(String, new com.cognitect.transit.handlers.StringHandler);
  a.set(Number, new com.cognitect.transit.handlers.NumberHandler);
  a.set(goog.math.Long, new com.cognitect.transit.handlers.IntegerHandler);
  a.set(Boolean, new com.cognitect.transit.handlers.BooleanHandler);
  a.set(Array, new com.cognitect.transit.handlers.ArrayHandler);
  a.set(Object, new com.cognitect.transit.handlers.MapHandler);
  a.set(Date, new com.cognitect.transit.handlers.DateHandler);
  a.set(com.cognitect.transit.types.UUID, new com.cognitect.transit.handlers.UUIDHandler);
  a.set(com.cognitect.transit.types.Keyword, new com.cognitect.transit.handlers.KeywordHandler);
  a.set(com.cognitect.transit.types.Symbol, new com.cognitect.transit.handlers.SymbolHandler);
  a.set(com.cognitect.transit.types.TaggedValue, new com.cognitect.transit.handlers.TaggedHandler);
  a.set(com.cognitect.transit.types.TransitSet, new com.cognitect.transit.handlers.TransitSetHandler);
  a.set(com.cognitect.transit.types.TransitArrayMap, new com.cognitect.transit.handlers.TransitArrayMapHandler);
  a.set(com.cognitect.transit.types.TransitMap, new com.cognitect.transit.handlers.TransitMapHandler);
  "undefined" != typeof goog.global.Buffer && a.set(goog.global.Buffer, new com.cognitect.transit.handlers.BufferHandler);
  "undefined" != typeof Uint8Array && a.set(Uint8Array, new com.cognitect.transit.handlers.Uint8ArrayHandler);
  return a;
};

specifically the clause:

"undefined" != typeof goog.global.Buffer 

Seems that goog.global isn't an object, and there was no working way for me to modify window/globals to get this to have some inject value (no window.Buffer or window.goog = window.goog || {} or globals.Buffer etc).

I tried a whole bunch of jest config settings and require vs import and all had similar issues.

The only thing I did note was that the "react-awesome-query-builder" from which this is a dependency includes node: {Buffer: false} in their webpack config. I tried setting this as well but to no avail.

The only other thing of note was that all other modules were imported but "transit-immutable-js" was required?

// react-awesome-query-builder/modules/import/tree.js 
const transit = require("transit-immutable-js");

Thoughts?
