The configuration of the media store S3Store , which maintains blobs in AWS S3, has changed. If you use a custom S3Store media store with an empty value for storeDir , no prefix for the blob path in the S3 bucket is applied now. The S3Store used to prepend an unnecessary / in this case. If you configure the S3Store by defining the property cap.server.blobstore.s3.bucketname , the default value for cap.server.blobstore.s3.rootdir is now an empty string and not blobstore/file as before.

If you use the S3Store explicitly and have configured an empty value for storeDir , change the value to / , so that the server expects the blobs in their old position.

If you configure the S3Store by defining the property cap.server.blobstore.s3.bucketname and do not set the property cap.server.blobstore.s3.rootdir so far, set cap.server.blobstore.s3.rootdir to blobstore/file , so that the server expects the blobs in their old position.

If you configure the S3Store by defining the property cap.server.blobstore.s3.bucketname and set the property cap.server.blobstore.s3.rootdir to the empty string, change cap.server.blobstore.s3.rootdir to / , so that the server expects the blobs in their old position.
