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

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

      My 50UT80506LA LG WebOs TV does not support my office security camera system via wifi to TV. We need (gCmob app) in list of app.

      It is unprofessional on part of LG TV that they do not resolve the basic issue of adding app gCmob in their app store.

      I can't connect my office camera via Wi-Fi to LG-TV. No body in LG TV technical team is proactive in resolving the issue of customer. They are more happy to befool the customers, rather than looking for technical solution through wider thinking.
      Please talk to you top management and make a visit to our office to understand the customers plight..
      Please respond to customers needs.

      BUG!!! Audio over ARC always muted since WebOS 5.5 update on lg-oled65c9pla
      By stevef
      Since my lg-oled65c9pla auto-updated to WebOS 5.5, there is a new bug.
      The TV is connected to my Cambridge Audio Evo 75 amplifier over ARC - on powering the TV, it has always started up the amp, and switched it to use audio, instead of the appalling TV speakers. The whole setup has worked flawlessly for 5 years, but since WebOS 5.5, the amplifier starts, but is left in a muted state, and using the un-mute or volume controls on the TV remote makes no difference to turning on audio. The only way to get audio to play though my amp a speakers is to turn the amp's volume dial or press a volume button on the a amp's remote - this then unmutes the TV and audio is back. 
      There is no setting I can find in the TV that relates to whether the ARC channel starts muted or not...
      No software has changed in my amp.  This is an annoying new bug in the TV software, I assume down to some CEC changes.
