immediate panic after selecting a provider

[zswanson]

Installed with brew, version 0.1.4
First time run, select either provider from the text menu. Immediate go panic and crash. Running on Mac M1, Monterey.
A colleague has the same issue on an Ubuntu VM running on Windows.

@zswanson, Prior to choosing the provider (AWS/GCP), the application requires the configuration of GOOGLE_APPLICATION_CREDENTIALS for GCP or the presence of a ~/.aws/credentials file for AWS.

Failure to locate the GOOGLE_APPLICATION_CREDENTIALS file or the ~/.aws/credentials file could potentially trigger a panic within the application.

Note: You can also use cloudlens gcp --cf <creds-file> command for GCP.

Hi @RamanaReddy0M,

I'm also getting the same error after setting the GCP credentials. It looks like it's due to not having permissions to fetch zones https://github.com/one2nc/cloudlens/blob/main/internal/view/app.go#L178C20-L178C30

10:15AM DBG Failed to list zones: Get "https://compute.googleapis.com/compute/v1/projects/my-project/zones?alt=json&prettyPrint=false": oauth2: cannot fetch token: 400 Bad Request
Response: {"error":"invalid_grant","error_description":"Invalid JWT Signature."}
