Research direction

Reproduce with a CloudFormation Number parameter using numeric AllowedValues and trace the prompt construction shown in inquirer/lib/objects/choice.js and choices.js. Confirm that numeric choices no longer trigger the TypeError, that the prompt accepts a value, and that the stack update proceeds.

Description

bug

Tried deploying a stack after adding an additional parameter with type: Number and AllowedValues provided:

e.g.

    LuckyNumber: {
      Type: 'Nuber',
      AllowedValues: [0,1,2,3,4,5,6,7,8,9,10]
    }

the stack update gets stuck before asking for LuckyNumber - it hangs until I stop the process and then it shows TypeError: Cannot use 'in' operator to search for 'value' in 0

I was able to reproduce this with two different repos.
After removing AllowedValues I was able to deploy without problems.
