Hovering the magnifying glass at the end of a log line should give you the project the error came from I think. ---

你好。对不起，我的中文不好。我希望你会说英语。😀 Yes as said before you can click on the mignifying glass and via the session-project you can find out which project generated the log. It also says from which exact user the message came. Some errors don’t show the magnifying glass though, finding that error becomes much harder… ---

If you have multiple projects repeating this View, I suggest refactoring and using a parent project for making future troubleshooting easier. ---

I dont think there’s anything inherently wrong with having a dozen projects. I just did a plant with 10, including the inheritable parent/gateway project. ---

The magnifying glass will show the path of the view, but we still can't determine which project it is. Because my project has a similar path. ---

We are engaged in industrial Internet of Things projects for the chemical industry. There are various clients and different requirements, so we will establish different projects. ---

Here, only the view path can be displayed, but it is impossible to determine from which project it comes. If there are similar views in the project, it would be very difficult to make a distinction. ---

You're right. I haven't studied the case of a father and son inheriting a project. ---

In your onMessageReceived scripts (or really any) using [system.util.getLogger | Ignition User Manual](https://docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-util/system-util-getLogger) could be helpful to improve the debugging output. ---

In the second screenshot the OP provided, you can see a logger called myLogger. Looks like they need to add more info to it. ---

Ah yeah, nice find. Using the sample code's logger name is not helpful ☹
