[nagaraju bolleni]

Hi I am trying to create branch in bamboo project plan through REST API ... through node js code . using post .

var Url =  http://localhost:8085 + 'plan/project/branch/branchName?vcsBranch="/poName"'; try{                    axios.post(Url, {}, {                    auth: {                    username:['username'],                    password: ['password']                   }

I am getting Request failed with status code 405 ...
