Memory leak warnings in electron - reactjs

Question

I'm getting memory leak warning in the console for my Electron app, i don't know what to do to increase limit. It's causing it everytime i run the app.
Does the error is linked to uiohook? Or did i miss something here?
How can i use emitter.setMaxListeners() in my case? I have no clue of how to fix it, and hwo to increase the memory leak.
