AuthFailure: Credential must have exactly 5 slash-delimited elements

Packer

hi, I’m using iam_instance_profile to build ami image in amazon and receive this error message while run packer build

mazon-ebs: error validating regions: AuthFailure: Credential must have exactly 5 slash-delimited elements, e.g. keyid/date/region/service/term

here my template:

{
“builders”: [
{
“ami_name”: “mediba-wordpress-{{isotime | clean_resource_name}}”,
“custom_endpoint_ec2”: “https://ec2.ap-northeast-1.amazonaws.com”,

I think people sometimes get this issue when they accidentally switch their access_key and secret_key

So, we need to provide aws credential even using instance profile?

For sure it’s not required to set the AWS credentials when using instance profile, btw is the issue resolved for you? If yes may I know what is the solution?
