Wildfly agent issue

I'm trying to run the disco agent with wildfly 19.0.0. It's acting as if if doesn't know where the disco-java-agent.jar is, but it obviously found it to initialize X-Ray.

Picked up JAVA_TOOL_OPTIONS: -javaagent:/Users/monty/lark/goldfinch/wildfly-config/wildfly-modules/software/amazon/disco/main/disco-java-agent.jar=pluginPath=/Users/monty/lark/goldfinch/wildfly-config/wildfly-modules/software/amazon/disco/main/disco-plugins

Any idea what might be going wrong?

Thanks!
