Feeder value #{WEB_ID} not recognized in ChainBuilder (Java) simulation

Not sure as you don’t provide the full code but I suspect you’re attaching feed to your scenario flow AFTER your requests.

In short, I suspect your doing:

exec(
http(“request_0”)
 .get(“/bhsol-pssd/prot/system-messages?webid=#{WEB_ID}”)
).feed(web_ids)

while your should be doing

feed(web_ids)
.exec(
http(“request_0”)
 .get(“/bhsol-pssd/prot/system-messages?webid=#{WEB_ID}”)
)
