Hey guys,

I´m using 3.4.0.beta3-dev, and I´m getting the mentioned error (but only in ui, not the logs) when trying to upload an image into a topic.

my config is thus:

```plaintext

["s3_upload_bucket", "<bucketname>/discourse-uploads"],
 ["s3_backup_bucket", "<bucketname>/discourse-backups"],
 ["s3_region", "eu-central-1"],
 ["s3_use_acls", "f"],
 ["enable_direct_s3_uploads", "f"],
 ["enable_s3_uploads", "t"],
 ["s3_access_key_id", ""],
 ["s3_secret_access_key", ""]]

```

and I´m using the ec2 instance profile and override the credentials

I get the error in ui:

but the log is telling me it was ok:

```plaintext

```

The bucket is empty afterwards (just setting this up with a fresh bucket)

Any hints ?

Thanks,

WS
