AEM Forms App MobileWorkspace: Running APK in Emulator throwing "Uncaught TypeError: text.replaceAll is not a function"


Level 1

Using adobe-lc-mobileworkspace-src-2.5.22 APK (AEM Forms App)

Android Studio Hedgehog | 2023.1.1 Patch 1 running on Windows 10 Desktop

Galaxy Tab S7 FE API 33 (Emulator) - We use that Tablet for our application (our employees)


I had to futz with the Gradle version (upgraded to 4.10.3/3.3.3) to get the APK to build - compatibility with Android Studio - but seems fine.


When accessing one of start points (that has been unmodified for several years) and works fine using the standard APK on our existing tablets... I get this error.


[INFO:CONSOLE(39890)] "Uncaught TypeError: text.replaceAll is not a function", source: http://fincare-dev.healthcareit.net:8080/lc/etc.clientlibs/fd/xfaforms/clientlibs/profile.js (39890)


The cordova.js has a standard fix (shim of sorts)

if(typeof String.prototype.replaceAll === "undefined") {
String.prototype.replaceAll = function(match, replace) {
return this.replace(new RegExp(match, 'g'), () => replace);
But obviously not seen by the mobile workspace in this context.
The profile.js appears to be some generated file by AEM that jams a bunch of stuff together.
Anyone have any ideas as to root cause and hence a way to the fix? Is it an Emulator issue? Is it something that I can fix server or client side???

Hi @RobinJo2 
I am not aware about solving issues for a device emulator. I think you can go for a general solution here so that you don't face above issue at other devices.
In these cases where advance/ or relatively new methods don't work. We can use 
1. Polyfills
Install as a dependency with npm i string.prototype.replaceall or yarn add string.prototype.replaceall;

Add the following code in your project. It need to be added in one place only.

import replaceAllInserter from 'string.prototype.replaceall';

Checkout if you can find some workable solution here : https://stackoverflow.com/questions/62825358/javascript-replaceall-is-not-a-function-type-error/7004...

2. Use original replace method :

I rebuilt my Emulator making sure it was Android 13 API 33 - I had select Android 11 API 30.

And lo and behold the problem vanished.

I blame Android madness.
