GNU Radio wx fft sink error

I have just started using GNU Radio Companion and was trying to follow Michael Ossmann’s lectures but got stuck at a very early stage. I have just connected an Osmocom source block to a WX GUI fft sink and somehow, the fft chart isnt opening. This is very basic stuff, I know, but I would be really very glad if someone could help me get started by explaining this to me. I have attached the error screenshot for reference.
