golang cdk: using cli sso profile adds slash in region

[jamesnealcontino]

What is the problem?

When using a cli sso profile to deploy a Go CDK app, an extra slash is added before the region.

Checking: "~/.aws/config - profile" shows just "region = ap-southeast-2"

the cli returns with "Unable to parse environment specification \"aws:///ap-southeast-2\". Expected format: aws://account/region"

full cli error log received:

panic: "Unable to parse environment specification \"aws:///ap-southeast-2\". Expected format: aws://account/region"

Reproduction Steps

aws sso login --profile

cdk init app --language go

return &awscdk.Environment {
	Account: jsii.String(os.Getenv("CDK_DEFAULT_ACCOUNT")),
	Region:  jsii.String(os.Getenv("CDK_DEFAULT_REGION")),
}

cdk deploy --profile

What did you expect to happen?

Expected cdk to deploy using the region within the chosen cli profile

What actually happened?

an extra slash is getting placed in front of the region

Other information

Looks like such a simple bug. Apologies. Have intentions of being able to fix these myself at some point. Wanted to kick it off by getting involved in any way possible.

@MrArnoldPalmer could you take a look at this?

[MrArnoldPalmer]

@jamesnealcontino Account: jsii.String(os.Getenv("CDK_DEFAULT_ACCOUNT")), if CDK_DEFAULT_ACCOUNT is not set this returns an empty string. So it is doing aws://account/region with account being "" resulting in an incorrect format. If you aren't explicitly passing an account, remove that line from your code so that Account is correctly nil and not empty string.

If an account is defined via the profile and CDK_DEFAULT_ACCOUNT is not set this is a bug with the CLI I believe. But it would break across all languages and we likely would have more reports.

if you do cdk --profile myProfileName --verbose MyStack this should output what account/region it is resolving. You can paste that output here but make sure to redact any sensitive information.

@rix0rrr are you familiar with any related problems in the CLI?

[jamesnealcontino]

Both "CDK_DEFAULT_ACCOUNT" and "CDK_DEFAULT_REGION" are being set through aws sso.

I actually can't run cdk synth due to getting the same "Unable to parse environment specification \"aws:///ap-southeast-2\". Expected format: aws://account/region"

It is resolving \"aws:///ap-southeast-2\" just it has an extra slash in it. Even though that slash is no where in the configs.

Is there an order in which the cdk will pull that region from? I'm only aware of ~/.aws/config which just shows ap-southeast-2

[MrArnoldPalmer]

Turns out this is because the cdk cli doesn't currently support named profiles via sso #5455

Gonna close this in favor of that issue.
