How to find the source for error : No historical tag information could be found

Ignition
1

I am encountering the following error every minute and need assistance in identifying which page is causing it. Despite disabling all the projects that I suspect might be triggering this error, it continues to appear. I have also changed the logger configuration from INFO to TRACE for tags.history.query.dataloader.DB , but the additional information has not been very helpful. Can anyone guide me on how to find the source page of this issue? I am aware that the tag name is configured incorrectly, but I need to determine which page is responsible. Thank you.

It's pretty difficult to trace this kind of thing down. If you've disabled all of the projects that you believe could produce this error, then it may be that you have leaked it and have an orphaned thread running on the gateway with incorrect code in it.

Have you tried restarting the Gateway? That will likely be the only way to kill an orphaned thread if that is what this is.

Otherwise, your best shot is doing a search with the Find & Replace tool for that string.

To anyone who might come across this, I had a very similar issue after making a tag change. The tag was referenced in a transaction group in a child project and was giving the same exact error every minute. Everything was fine and the path was correct. Long story short save your projects, close your designers and ignition gateways. Issue was resolved for me upon re-opening project.
