Symptoms

Applications fail to read the <StorageClass> when listing a bucket.
The field is missing in the return.

Cause

Applications checking for <StorageClass> wont be able to proceed as the field is missing in the xml file returned by the ECS.
At this point Storage Class is not used in ECS and always should returns "Standard". 
<StorageClass>STANDARD</StorageClass>

<StorageClass>STANDARD</StorageClass>
However, some applications may depend on return of this value.

Example Response in 3.7: 
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ListBucketResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
  <Name>mike-s3</Name>
  <Prefix/>
  <Marker/>
  <MaxKeys>1000</MaxKeys>
  <IsTruncated>false</IsTruncated>
  <ServerSideEncryptionEnabled>false</ServerSideEncryptionEnabled>

      <DisplayName>mike</DisplayName>
    </Owner>
    <IsFanoutObject>false</IsFanoutObject>
  </Contents>
</ListBucketResult>
 

Resolution

The issue will be fixed in 3.7.0.2
As a temporary workaround the application can list the bucket using the "?versions" tag on the list command:

Example: 
sudo perl ./s3curl.pl --id xxx -- -v "http://10.x.x.x:9020/mike-s3?versions"| xmllint --format -
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ListVersionsResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
  <Name>mike-s3</Name>
  <Prefix/>
  <KeyMarker/>
  <VersionIdMarker/>
  <MaxKeys>1000</MaxKeys>
  <IsTruncated>false</IsTruncated>
  <Version>
    <Key>20220308_231130_run_Health_Check.zip</Key>
    <VersionId>null</VersionId>
    <IsLatest>true</IsLatest>
    <LastModified>2022-03-09T18:24:39.604Z</LastModified>
    <ETag>"35f6f6e4fdb993e792b4865249ecc0c8"</ETag>
    <Size>96662</Size>
    <Owner>
      <ID>mike</ID>
      <DisplayName>mike</DisplayName>
    </Owner>
    <StorageClass>STANDARD</StorageClass>
  </Version>
</ListVersionsResult>
