Errors in console

When I log in from workplace, I have a lot of these errors in my browser’s console:

How can I address the ones in the red box?

For the other ones, the websocket connection errors, what kind of network setup should I ask our IT dept?
I guess that solving those will solve the unresolved promises too.

Thanks

I may be mistaken but I think the DOMWindow errors are to do with a Custom domain and should not affect anything. I do remember asking support this same question some time ago and I think response was that this can be safely ignored.

Hello @rick and thanks for helping.
I see you’re probably referring to this forum post where user mail says:

it worked just fine before I moved it to my custom domain,

In my case there is no custom domain though, it all happens between anvil.works and …anvil.app, and these are all “official” Anvil domains.

Besides, the questions on websockets remains open to any help available.

Thanks and BR
