Hello @Hardy Wang 

Welcome to the Atlassian community.

Your post tags indicate you are using Jira Cloud, but the Jira URL you are showing is "jira.jaguarmicro.com". That suggests to me that you are not using the Jira Cloud product, which is a software-as-a-service product, but rather are using Jira Server or Jira Data Center.

Can you log in to your Jira instance and click on the Help button in the upper right corner and then select About and share with us the information you find there?

Prior to executing that API call, have you executed the necessary API calls to establish an authenticated session with the target system and the Jira product?
