Dashboard Javascript Errors

I am getting frequent javascript errors in browser local Dashboard windows, even in dashboards with no tiles. Both Chrome and Edge have this issue. The errors are similar to one of the errors listed in:

Uncaught TypeError: Cannot set properties of undefined (setting 'value')
at v.SOCKET_ONMESSAGE (app.js?t=2.3.3:1:313162)
at chunk-vendors.js?t=2.3.3:13:5727
at chunk-vendors.js?t=2.3.3:13:6761
at Array.forEach ()
at chunk-vendors.js?t=2.3.3:13:6740
at v._withCommit (chunk-vendors.js?t=2.3.3:13:8302)
at v.commit (chunk-vendors.js?t=2.3.3:13:6714)
at v.commit (chunk-vendors.js?t=2.3.3:13:3395)
at t.value (chunk-vendors.js?t=2.3.3:28:69330)
at t.value (chunk-vendors.js?t=2.3.3:28:68904)

I have a C-7 running 2.3.5.121.

Is this a known problem?

This error happens when the browser js receives an event message from a Hub Variable that the Dashboard has not been configured to access.

There are none of these uncaught errors if the Dashboard is (unnecessarily) configured to access all of the Hub Variables. However, then a new type of error is caught:

app.js?t=2.3.3:1 ReferenceError: devices is not defined
at v.SET_GLOBAL_VARS (app.js?t=2.3.3:1:305205)
at chunk-vendors.js?t=2.3.3:13:5727
at chunk-vendors.js?t=2.3.3:13:6761
at Array.forEach ()
at chunk-vendors.js?t=2.3.3:13:6740
at v._withCommit (chunk-vendors.js?t=2.3.3:13:8302)
at v.commit (chunk-vendors.js?t=2.3.3:13:6714)
at commit (chunk-vendors.js?t=2.3.3:13:3395)
at app.js?t=2.3.3:1:317585

@support_team I don't know if these errors cause any serious problem, but they at least fill up the console log and make it hard to find other issues.

What version of java are you using?

Are you asking what version of javascript is built into the browser? How can I determine that?

It may not sound like much, but getting a "Noted..." from Gopher is a big deal.
