Escape gatling expression language syntax in file passed to ElFileBody


Is there a way to escape the gatling expression language syntax in a file that is passed to ElFileBody? The same syntax is used in our BPMN definition resulting in the following error:

Simulation started…
09:40:29.537 [ERROR] i.g.h.a.s.HttpRequestAction - ‘httpRequest-3’ failed to execute: No attribute named ‘PERFORMANCE_1==“yes”’ is defined

exec(http("Create Definition")

PeformanceDefinition.json contains the following line:

Nope. There was a long standing issue for this but it was finally closed as it didn’t get any traction (you’re the first one to ever ask, while Gatling has been around for 6 years).
