This error is caused by the function below:

function p(e, r = !1) {
                    let n = Object.keys(t.webpackRequire.m);
                    r && (n = n.reverse());
                    const o = setTimeout(() => {
                        a(`Searching for: ${e.toString()}`);
                    }, 500);
                    for (const r of n)
                        if (!f(r))
                            try {
                                const n = (0, t.webpackRequire)(r);
                                if (e(n, r)) return a(`Module found: ${r} - ${e.toString()}`), clearTimeout(o), r;
                            } catch (e) {
                                continues;
                            }
                    n = Object.keys(t.fallbackModules);
                    for (const r of n)
                        try {
                            const n = t.fallbackModules[r];
                            if (e(n, r)) return a(`Fallback Module found: ${r} - ${e.toString()}`), clearTimeout(o), r;
                        } catch (e) {
                            continues;
                        }
                    return a(`Module not found: ${e.toString()}`), null;
                }

The steps to reproduce the issue are:

1. Login Whatsapp scanning QR code (whatsapp version > 2.3000)
2. Manual inject wa js in console (single time)

WPP.isInjected is always False

Whatsapp is delivering js that is incompatible with the lib when you have the "wa_build=c" cookie set.

To fix it, set the cookie to any other value, then reload the page:

document.cookie = "wa_build=w;domain=.web.whatsapp.com;path=/";

For me, Whatsapp is setting this cookie every time I reload the page, forcing me to set another value for the cookie every time.

the problem seems that in the 2.300 version, the injected code wrongly set the WPP.webpack.loaderType = "webpack" instead of "meta".

Maybe a solution is adding a check of wa web version In the injectLoader function, replacing these lines

, n = "webpackChunkwhatsapp_web_client"
, o = e[n] || [];
 void 0 === e[n] ? e[n] = o : t.loaderType = "webpack";

with

,n="webpackChunkwhatsapp_web_client"
,o=e[n]||[];
const versionString = (Debug || {}).VERSION;
const versionNumber = parseFloat(versionString);
if (void 0 === e[n]) {e[n] = o;} else if (versionNumber < 2.3) { t.loaderType = "webpack";}
