Fails to get active window on macOS

Mac OSX 10.12.6 Sierra, running all modules + aw-watcher-spotify + aw-watcher-web Python 3.6.3 :: Anaconda, Inc.

I added the last heartbeat for debugging purposes

and then the same error keeps on getting repeated –

Please let me know if you need the log files

Hello all. I experienced this as well, it’s not fatal, but it came up when running in the terminal. The context was that Firefox crashed while I was away from the computer and for a while, there might not have actually been an active window? The status messages went back to normal after focusing on other windows. Unfortunately, I have not been able to reproduce the issue despite trying to get into situations with no active window.

It seems like https://github.com/ActivityWatch/aw-watcher-window/blob/cea4bf048ed9e4af66445bff5015e38c510ec892/aw_watcher_window/macos.py assumes that there will always be an active window.

In the AW gui, the watcher_window shows “unknown” for this time period. That seems reasonable as-is, so perhaps the “solution” here is silence the error?

@Patrick3131 Yes that’s why it’s failing. To test the command either move back activitywatch to the Downloads folder or enter the new path to the printAppTitle.scpt in the command.
