Chrome WebView and Android 15 Script Error --- What is it and how do I fix it?

Holydoc · May 14, 2025, 8:03pm

I do not understand how to correct this error that keeps popping up in my Home Assistant Core Logs.

Logger: frontend.js.modern.202505090

Source: components/system_log/init.py:331

First occurred: 2:34:29 PM (2 occurrences)

Last logged: 2:49:40 PM

Uncaught error from Chrome WebView 136.0.7103.60 on Android 15 Script error. null @:0:0

I have attempted to clear the cache on my Chrome web browser on my Galaxy Phone. I also do not use Chrome to connect remotely to Home Assistant with my phone. I use the HA Companion app.

I do use Chrome to talk to HA at home. However I am not using Chrome from home currently since I am at work and only access HA using the Companion App.

Why am I getting this error and how do I correct it?

I have the same problem, and it’s caused by the Home Assistant companion app on different Android versions (10, 14, 15) across my devices. This doesn’t happen with the browser or the Chrome-installed web app.
