Do you mean that you cannot synchronously validate the file and return an error to the client? For async validations a lambda on an s3 trigger works well enough

For async validations a lambda on an s3 trigger works well enough. For sync validation I've found you are limited in what you can encode in an upload policy
- gw98 4y agoCan't do that. The clients own the S3 buckets not us. The whole idea we had was stupid.
- alserio 4y agoYou still can use POST policies, they don't need to be defined on the bucket but only signed. But you are limited on what you can check. Other than that, yeah, the approach might not have been adequate.
