While i am creating a new component in angular cli i get the above error as Invalid rule result: Instance of class Promise.

Tried deleting the node_modules and installing the dependencies again. Kindly help me on this.

After looking at StackOverflow, I found this answer. Seems like a mismatched schematics version. Would you try the answer and let us know if everything works?
