Error anytime Save is pushed

Ignition

Hello,
I'm getting an error every time I click the save button, cant figure out whats causing it. It still saves any changes I make but I keep getting the error. I pasted the error message from output console.

What version are you on? This should be fixed in 8.3.3

Im on 8.3.2, I'll update and see if that fixes it. Thanks!

In case that does not fix it, I have also seen this issue a couple times. It has only happened to me when there are multiple developers editing the same project in Ignition Designer. Seems the Session Properties can get a little out of whack. I was able to resolve by selectively saving the page updates, then closing and exiting. When you reload, the page changes will be there because you selectively saved them, and the session properties will be re-synched with the gateway.
