Question on JavaScript Errors with Next.js Application on WebOS 6.0

[RCMiller]

Greetings,

I'm hoping someone can assist with a problem we're experiencing while running a Next.js based web application on WebOS.

Our Configuration:
Display:  43UM5N-E UHD Signage Display (43" LCD)
WebOS version:  6.0.0-124 (libertyspikes-lager)
Next.js version:  16.0.3
React version:  19.2.0

We have built a web application using Next.js and React.  It is hosted on an IIS server running on our local network.  The display is connected to the same network and we have verified connectivity with the web server.  Our application is not a native WebOS app, but rather, we are using the Play via URL option to display the web site when the display boots up.

Attached is an image of the errors captured while running in the WebOS 6.0 simulator.  These errors happen immediately after the application starts.

Based on our research, the embedded version of Node.js on this display is 8.12.0.  On newer versions of the simulator (v22 and above), the application loads fine and no errors occur.  It seems there are JS incompatibilities between the newer Next.js framework and the version of JS build into this display.

Questions:
1. Can the embedded JS version of the display be upgraded, and if so, how?
2. Is there any other possible workaround to get this application to load?  It runs fine on regular browsers and reverting back to an older version of Next.js or re-writing in plain JS is not an option for us.

Any suggestions or help is appreciated!

Thank you,
Bob Miller
