Jamming project stuck on exercise 34 please help, not work

Hello. Please can somebody help me. It still doesn’t work for me. Stuck in task 34.
I saw that wrote about the Jammming project. I read it all but the program still doesn’t work for me.

TypeError: this.props.isRemoval is not a function.

A link to the project would be helpful, as would a copy of the code you’re running.

At a guess, though, since the error is:
TypeError: this.props.isRemoval is not a function.

I’m guessing you’re trying to invoke something as a method - i.e. some_object.isRemoval() - which isn’t a method, but a property.
