Description:
[S3 Test suit
failing|https://ozone.s3.peterxcli.dev/?q=test_put_obj_with_tags&run=2026-05-17T05-56-28Z&caseSuite=s3_tests&test=test_put_obj_with_tags#search-section]
This JIRA addresses issues in the *object tagging* implementation:
*Null Tag Value Support for x-amz-tagging-header:* The S3 Gateway validator
currently rejects x-amz-tagging on put object tags with a null value string
(e.g., {{{}Key=TagA, Value{}}}) with an {{InvalidTag}} error. AWS S3 permits
null tag value to be considered as empty string values. This causes
{color:#de350b}{{test_put_obj_with_tags}}{color} to fail.
While a normal put-object-tagging is correctly rejecting null tag value.
{code:java}
// wrong behaviour
// put object with x-amz-tagging header with null tag value should be treated
as an empty value.
bash-5.1$ aws s3api put-object --bucket buck1 --key key1 --tagging 'tag1'
--endpoint-url http://s3g:9878
An error occurred (InvalidTag) when calling the PutObject operation: Some tag
values are not specified, please specify the tag values
// no tags applied which is wrong
bash-5.1$ aws s3api get-object-tagging --bucket buck1 --key key1
--endpoint-url http://s3g:9878
{
"TagSet": []
}{code}
*Proposed Fix:*
Update *{{validateAndGetTagging()}}* in {{EndpointBase}} to allow values with
zero length when x-amz-tagging header is present else on normal put object
tagging this null tag value should fail, while maintaining the requirement that
the Key must have at least one character.
After fix:
{code:java}
// put object with x-amz-tagging header succeded for null tag value
bash-5.1$ aws s3api put-object --bucket buck1 --key key1 --tagging 'tag1'
--endpoint-url http://s3g:9878
{
"ETag": "\"d41d8cd98f00b204e9800998ecf8427e\""
