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.

[RamanaReddy0M]

@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

It seems to try to access IMDS, but I'm using my personal computer

[francilioaraujo]

Debugging the code I saw these lines but didn't understand if it should work

cloudlens/internal/view/app.go

Lines 102 to 112 in 167bc6b

	var err error
	profiles, err = readAndValidateProfile()
	if err != nil {
	panic(err)
	}
	if len(profiles) > 0 {
	if profiles[0] == "default" && len(region) == 0 {
	region = getDefaultAWSRegion()
	} else if len(region) == 0 {
	region = "ap-south-1"
	}

I am explicitly setting a profile using the environment variable AWS_PROFILE (also AWS_DEFAULT_PROFILE and AWS_EB_PROFILE), but these lines are setting the default profile nonetheless. What is the point of overwriting the chosen profile?
