Error: java.lang.NullPointerException: Parameter specified as non-null is null #82

Closed CatchABus closed 1 year ago

CatchABus commented 2 years ago

If one gives a null value as a text to method fillText an exception will be thrown. In web, fillText may accept null value as a text.

In my case, it was chart.js itself that attempted to append a null parameter.

System.err: An uncaught Exception occurred on "main" thread.
System.err: Calling js method contextReady failed
System.err: Error: java.lang.NullPointerException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkNotNullParameter, parameter text

I think browser is using something like param + "" internally by default. In my screenshots, I try to append different types apart from string. Screenshot from 2022-08-05 01-25-53 Screenshot from 2022-08-05 01-26-58 Screenshot from 2022-08-05 01-27-16 Screenshot from 2022-08-05 01-27-38
