Hi All,
I am currently working on redmine connector improvement. For that when we
get empty response body from API, it's returning error as below.
For example, response from the API for the delete method
if it is deleted - 200 OK
if it is not exist - 404 not found
we are getting status code only, but empty response body.
The needed action is working fine[1]. But it is returning error as below[2].
I am testing these methods using ESB 4.9.0, also I had test with 5.0.0 M2
as well.
Error Log,
