[jira] [Commented] (HDDS-2630) NullPointerException in S3g
[ https://issues.apache.org/jira/browse/HDDS-2630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16989402#comment-16989402 ]

------------------------------------------
Hi [~Sammi]
I see NPE is because auth header is not set. Not completely sure in which case auth header will be null from S3 clients (like aws cli ..) Here we are hitting NPE because the auth header is not set.
In the working scenario. In the virtual host style filter, we set the auth header, and that header will be used during bucket creation. As in S3 volume is generated from access key id, which we get from authentication header.
I see we can have a Precondition check not NULL before actual parsing auth header and fail the request. But want to understand in which type of scenario's authentication header will be null
Debug logs for testing I have added, to show the flow.
