Greetings –
I switched from 2.2.0-M3 to 2.2.0-SNAPSHOT. The (few) user-visible API changes were easy to deal with (e.g., io.gatling.core.validation.Success → io.gatling.commons.validation.Success). However I ran into unexpected behavior that looks like a bug; here’s the relevant code fragment:
val pb = http
.proxy(Proxy(“localhost”, 8888))
.baseURL(endpoint)
// etc.
The simulation works fine with the proxy line commented out; bringing it in generates a NPE:

If it matters I run the simulation via the sbt plugin.
Thanks,
