HTTP-REST null pointer exception

Hi All,

I have configured http host and rest operation . It throws null pointer exception "java.lang.NullPointerException (Workflow:Get TLAs / Scripting (item3)#16)". It throws when calling response = request.execute(); All certificates are imported i.e host and issuing authority .

There were some cert errors before the import. HTTP-PROXY and Basic authentication is set during host configuration. There is no issue with the URL. It works fine in SOAPUI client. There are no exceptions in the log file.

VCO 5.5.1

HTTP-PROXY plugin 1.0.3

Any help appreciated.
