'Weed Filer backup errors in the log

I started a weed filer.backup process to backup all the data to an S3 bucket. Lot of logs are getting generated with the below error messages. Do i need to update any config to resolve or these messages can be ignored?

s3_write.go:99] [persistent-backup] completeMultipartUpload buckets/persistent/BEV_Processed_Data/2011_09_30/2011_09_30/GT_BEV_Output/0000000168.png: EntityTooSmall: Your proposed upload is smaller than the minimum allowed size

Another message

malformed xml the xml you provided was not well formed or did not validate against

This issue happens with empty files or files with small content. Looks like aws s3 multipart upload does not accept streaming empty files. Is there any setting on SeaweedFs that i am missing?
