Getting `TypeError: Cannot read properties of undefined (reading 'end')` on a function parameter
matyasf opened this issue · comments
This is the code on in the component that triggers the exception:
onUpdate?: ({ visibleItemsCount }: { visibleItemsCount: number }) => void
(this is in the type of the props
for a class based component)
The full stack trace is:
TypeError: Cannot read properties of undefined (reading 'end')

Thanks for reporting this. 💙
I fixed this and it is released in version 6.0.3
This went undetected, because the types of babel in that case were wrong: babel/babel#15867
