Describe the bug

I started out with amplify cli 4.48. I am working with another dev who is using version 4.50. If I update to 4.50 and then try to amplify push I get the following error: Cannot read property 'length' of undefined

After reverting to 4.48 I can amplify push again.

Additionally, I set up amplify frontend hosting with github ci before I noticed this problem. I went to check those frontend environments and it looks like after the other developer pushed to the github branches that those frontend environments are connected to, they stopped building successfully.

Looking at the errors on those environments, they are having the same problem I ran into when I tried to update my amplify CLI to 4.50.

2021-05-01T03:41:34.837Z [WARNING]: ✔ Initialized provider successfully. 2021-05-01T03:41:35.009Z [WARNING]: ✖ An error occurred when pushing the resources to the cloud 2021-05-01T03:41:35.010Z [WARNING]: ✖ There was an error initializing your environment. 2021-05-01T03:41:35.013Z [INFO]: �[0mTypeError: Cannot read property 'length' of undefined�[0m

Expected behavior

I should be able to update my amplify vli and then amplify push without running into an error.
Also, my amplify frontend envs should be able to build.

Reproduction steps

1. Pull an amplify project while using amplify cli 4.48
2. update amplify cli to 4.50
3. try to amplify push
