Hello,
do you check that header_name parameter set for KSR.hdr.is_present() is a string value?

Hi,
Intermittently we are observing the following error when checking if given header is present in SIP INVITE:
SystemError: returned a result with an error set

The above exception was the direct cause of the following exception:
