Error ScriptEvent design web station

[Martinmx]

Good day,
I've been having trouble viewing designs in Web Station, do you know why this is?
I work with version 5.0.3.

These designs are now over two years old and it wasn't until after the update from version 4.0 to 5.0.3 that I started experiencing these errors.

It happens to me even with unconfigured components, in this case with an analog display

@Martinmx "MutationEvent is not defined" Javascript errors are displayed after Chromium based browsers (Chrome or Microsoft Edge) are updated to version 127. As referenced in Mutation events will be removed from Chrome  |  Blog  |  Chrome for Developers, Google has deprecated these Mutation events and replaced them with a different function.

Hotfixes are currently being tested for the issue but in the meantime you can apply the temporary mitigations noted below to allow the previous functionality until March 2025.

Google Chrome browser:

• Type chrome://flags/#mutation-events and change the highlighted setting to enabled. Then restart the browser.
• There is also an Enterprise Policy called MutationEventsEnabled that functions similarly for enterprise users. 

MS Edge browser:

• type edge://flags/#mutation-events into the browser address bar and change the highlighted setting to enabled. Then restart the browser.
• Enterprise users can use the MutationEventsEnabled policy
