Note that this issue comes and goes. It did not work for (maybe) a week, then worked for 2 days, now doesn't work again with a slightly different error: "Cannot read properties of null (reading 'push')"

I see this error very often as well. I'm getting used to this extension just not working at all, and am surprised the few times that it is working. My environment is entirely different than the OP's, so probably not related to the environment at all, but maybe an entry in our database that is causing this problem?

PS: while drafting this bug report, the Chrome extension crashed. I reloaded it and it again found all my passwords. Maybe this is related to not shutting down the browser all that often (and a session going stale?)
