Unable to open a perspective view in designer


I can not open one of my views in the designer everything else opens fine but one of the view is stuck in loading and I get this error. It was opening until yesterday.

java.lang.Exception: Unable to get the view config: View config is undefined.

What did you do yesterday?
Using any 3thparty modules?

You might be able to recover something if you adjust the sourcefile. (make a copy first!)
C:\Program Files\Inductive Automation\Ignition\data\projects\YOURPROJECTNAME\com.inductiveautomation.perspective\views\YOURVIEWNAME\view.json

making adjustments to the source files dont immeditalty get registered by the gateway so restarting or waiting might be needed
