I have a problem using the Custom Identity Provider, I am trying to setup the SFTP Transfer service using this page: https://docs.aws.amazon.com/transfer/latest/userguide/authenticating-users.html
I used this template https://s3.amazonaws.com/aws-transfer-resources/custom-idp-templates/aws-transfer-custom-idp-basic-apig.template.yml to create my CF stack and when I test authentication using the SFTP Transfer console I get the following:
{
"Response": "{"Role": "arn:aws:iam::0000000000:role/s3-sftp-transfer","HomeDirectory": "/"}",
"StatusCode": 200,
"Message": "",
"Url": "https://xxxxxxxxx.xxxxxxxx.amazonaws.com/prod/servers/s-xxxxxxxxxxxxxxxx/users/myuser/config"
}
According to the documentation, what I am getting in the "Response" field, should be in the "Message" field, and when I test with the AWS CLI test-identity-provider, I get the URL and statusCode, but again the "Message" field is blank.
Does anyone have any idea what I am doing wrong, or what I could check?
I manually tested the Lambda and the API Gateway and they both seem to work. I am not sure where to look next.
Thank you!
