[profile staging]
region=ap-northeast-1
output=json
credential_process = "/home/ubuntu/staging.sh" "--username staging"

@MarryYou - have you already looked through #1656
Are you using credential_source? A workaround is suggested for getting around that as it's not currently supported.

@shivlaks Hi shivlaks thank you for your reply. According to the issue you provided, I changed the way of using the certificate and now it can work normally.I suggest that assme Role be added to the credential usage of CDK, which is a common usage scenario.

We do support assuming a role but I think I'll make some updates to our documentation and add some better examples.
