    Can you tell me why this occurs?

    Thanks in advance!

    Most likely the cookieVal contains NULL. This can happen if there’s no cookie with the name provided (cookiname).

    I would suggest putting a breakpoint on line 17 and inspect the cookieObj whilst debugging. There you will be able to see whether the cookie exists or not in the object.

    thanks for the assist. Worked perfectly.

    Just found out in certain Mule versions this does not work anymore with the new HTTP connector. message.getInboundProperty(“Set-Cookie”); returns only the first cookie, instead of an array. This is solved in Mule 3.6.3, 3.8.0 M1 and Mule 3.7.3. See https://www.mulesoft.org/jira/browse/MULE-8790.
