is there any limitation to the aws engine document parameter size?
Hi. There is no limit that Vault imposes. Are you seeing otherwise?
Yes seems like there is a limit of 2048 bytes. It will let you store the policy but once you read creds, it gives this error saying it has a maximum limit of 2048 bytes.
It looks like that’s an AWS limit, or at least the default quota prior to an increase: IAM and STS quotas - AWS Identity and Access Management
