I'm facing a weird behavior in the designer, when I copied a view and pasted it in the same folder, I got this blank white screen in both the original and the copy views, then when I try to close the view, I get this error in the screenshots. It started happening when I tried to copy a json into a view, but it was in a totally different gateway in a totally different docker container. Now, it's happening in the other gateway in the other container somehow!! PS: The views both original and copy are working fine when I embed them in other views or open them in a perspective session. Any ideas? Thanks ![Screenshot from 2024-09-30 09-36-38](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/3/f3e7f40a1e955f77cb1de0640fbc8a88c249460c.png) ![Screenshot from 2024-09-30 09-37-03](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/8/58f0107e2b1289a14af14f464e4786a5a5d6591e.png) ![Screenshot from 2024-09-30 09-37-07](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/7/7707db72208788f99dfdb38d5d4bb7e89310e5fd.png) ---

Is this gateway hosted behind a reverse proxy? We recently encountered another similar situation where a rewrite configuration in a reverse proxy was inducing some escaping issues that caused this same error. ---

No, it's not hosted behind any reverse proxy. ---

If this happens again, can you review the logs in the _Console_ (can be shown via the _Tools_ menu) within the Designer? There might be some more helpful information there to correlate with this exception dialog. ---

@kcollins I know you weren't asking me directly, and my issue might be different, but I am getting the dreaded `Unable to get the view config: View config is undefined` error and here is the log from the console. For me, it seems the "busier" the view, the more it happens. I usually hit save and try again, it will usually open after a few tries, so there definetely isn't anything wrong with the view. I opened a ticket a while back and IA support never could find the issue, maybe you can take a stab? ```python 17:01:24.964 [Browser Thread: c09d33ea-02fc-4bee-aaec-844cf11e4e01] ERROR Perspective.Designer.Workspace -- level: LEVEL_ERROR message: "TypeError: Cannot destructure property \'width\' of \'this.rootViewDefaultSize\' as it is undefined." line_number: 121 source: "http://localhost:8088/res/perspective/js/react-dom-18.2.0.js" 17:01:24.964 [Browser Thread: c09d33ea-02fc-4bee-aaec-844cf11e4e01] ERROR Perspective.Designer.Workspace -- level: LEVEL_ERROR message: "onerrorLogger: {\"stack\":\"TypeError: Cannot destructure property \'width\' of \'this.rootViewDefaultSize\' as it is undefined.\\n at get selectionDimensionsClientBoundingRect (http://localhost:8088/res/perspective/js/PerspectiveDesigner.1ea4fc945c965fd69d63.js:2:250719)\\n at oe (http://localhost:8088/res/perspective/js/mobx-5.15.7.js:15:5475)\\n at t.computeValue (http://localhost:8088/res/perspective/js/mobx-5.15.7.js:15:11912)\\n at t.trackAndCompute (http://localhost:8088/res/perspective/js/mobx-5.15.7.js:15:11738)\\n at t.get (http://localhost:8088/res/perspective/js/mobx-5.15.7.js:15:10670)\\n at e.read (http://localhost:8088/res/perspective/js/mobx-5.15.7.js:15:39612)\\n at b.get (http://localhost:8088/res/perspective/js/mobx-5.15.7.js:15:41065)\\n at get selectionDimensions (http://localhost:8088/res/perspective/js/PerspectiveDesigner.1ea4fc945c965fd69d63.js:2:251204)\\n at oe (http://localhost:8088/res/perspective/js/mobx-5.15.7.js:15:5475)\\n at t.computeValue (http://localhost:8088/res/perspective/js/mobx-5.15.7.js:15:11912)\",\"message\":\"Cannot destructure property \'width\' of \'this.rootViewDefaultSize\' as it is undefined.\",\"name\":\"TypeError\",\"logData\":{\"msg\":\"Uncaught Exception\",\"errorMsg\":\"Uncaught TypeError: Cannot destructure property \'width\' of \'this.rootViewDefaultSize\' as it is undefined.\",\"url\":\"http://localhost:8088/res/perspective/js/react-dom-18.2.0.js\",\"line number\":198,\"column\":64}}" line_number: 2 source: "http://localhost:8088/res/perspective/js/PerspectiveClient.b21ef825efc08df9dea8.js" 17:01:24.964 [Browser Thread: c09d33ea-02fc-4bee-aaec-844cf11e4e01] ERROR Perspective.Designer.Workspace -- level: LEVEL_ERROR message: "Uncaught TypeError: Cannot destructure property \'width\' of \'this.rootViewDefaultSize\' as it is undefined." line_number: 198 source: "http://localhost:8088/res/perspective/js/react-dom-18.2.0.js" ``` ---

@jlandwerlen, thank you for the stack trace. It actually looks like there was a ticket that might have addressed this specific error in 8.1.44. It is under IGN-9290 in our system. See this post from @avaughn over [here](https://forum.inductiveautomation.com/t/view-undefined-ongoing-needs-a-fix/95752/3). ---

You might investigate what kinds of rewrites you might be doing in your reverse proxy configuration. We've observed (separate ticket IGN-11526 on our side) some reverse proxy setups defaulting to rewriting URLs in ways that negatively impact Perspective.
