Open shahbazshoukat opened 9 months ago

shahbazshoukat commented 9 months ago

Is this a support request? The issue is in SDK.

Describe the bug I am encountering a console warning related to memory leakage. The warning message is as follows:

Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in the componentWillUnmount method.

To reproduce Use LDProvider component:

Expected behavior There should not be any memory leakage warning in the console when initializing the Launch Darkly.

Hello @shahbazshoukat, thank you for reaching out with this report. We will look into this. Just to check, is this happening during development (using something like hot reload) or inside a production application?

It's a React warning so you see it only in development.

It's not blocking the application but it means there is something wrong in conception.

I have the same problem
