I tried writing a proxy service in the ESB to get the project details from jira using getProject method and then create that project in redmine using createProject if it is not already created in it. I have used the jira and redmine connectors in ESB. The proxy I have written is shown in [1].
When I send the request to the proxy using SoapUI I get an error [2]. But the project of which the details were taken from jira if not present in redmine has been created in it. How can I fix the issue of getting an error ?
