Hi @Prasanth. How can you tell the 3gpp-sbi-message-priority header is dropped?
I just did some testing locally (see attached screenshot) with your script and everything seems to work fine on my end.
Try running your test with the --http-debug="full" (i.e: k6 run k.js --http-debug="full") flag and monitor requests to check whether the header is being sent or no.
