"onChange is not a function"

[Redblock6YT]

I'm using nextjs and when I click the switch this is the error I get:

Here's my code:
<label> <span>Switch with default style</span> <Switch onChange={handleChange(1)} checked={isActive(1)} /> </label>

It looks like you're invoking the handleChange function which means you're passing whatever that function returns to the Switch component. You should be passing the function itself.
