Hello GoJSers, I started using GoJS recently and it’s, as Keanu Reeves would say, BREATHTAKING. However, an error pops up in my console from time to time. The error says Uncaught TypeError: Cannot read property 'isEnabled' of null at HTMLCanvasElement.push../node_modules/gojs/release/go.js.R.Mz (go.js:636)
. From what I’ve checked under my code, this property isEnabled doesn’t appear anywhere. What am I missing, someone had this same error before or? How can I fix this?
There are several “isEnabled” properties defined in the GoJS API, as you can find at: GoJS API
I have no idea of what might be going on in your app.
So there isn’t actually a way to catch where this error comes from?
The first thing to try is using the go-debug.js
library and seeing if there are any warnings or errors in the console window.
BTW, there’s no function named “Mz” in the latest release of go.js
. I’m guessing that you are using an older version?
My guess is that the HTMLDivElement that is supposed to host a Diagram hasn’t been associated with a Diagram yet.
Thank you for the kind reply :) This explains it
