I am updating the runtime version of an application in cloudhub(anypoint platform - mulesoft).
In detail, updated the runtime 3.9.0 -2018 release to runtime 3.9.0 - 2019 latest version. I am able to successfully deploy the application and it is started without any issues.
Later, When I am trying to make HTTP request to application. It errors out as below ::
ERROR

********************************************************************************
Updating Mule 3.9.0 in CloudHub to the October 24 2019 release should resolve that issue.
Having said that, I usually recommend to also upgrade to the last version, 3.9.3, which includes many other fixes.
