Hello @Yang LV
Welcome to the Atlassian.community.
You are asking about a specific issue in a specific Jira instance. You will need to contact the owner/administrators of that system about your question.
Here we are a user community. We are users of our own Jira instances and don't have access to the instance you are using.
If you have questions in general about Jura functionality or error messages we can help you with those.
