No CSV report files being generated (java 17 and Gradle 7.4.2)

I'm using gradle and the ZeroCodeMultiLoadRunner to run some load tests and the tests execute correctly but no csv files are being generated in the target folder, only target/logs/zerocode_rest_bdd_logs.log and the regular junit output in build/test-results. What am I missing?

This is part of my gradle file - I'm running the tests in a separate source config:

~~~
sourceSets {
loadTest {
java {
compileClasspath += main.output + test.output
runtimeClasspath += main.output + test.output
srcDirs = ["src/loadTest/java"]
}
resources {
srcDirs = ["src/loadTest/resources"]
}
}
}

configurations {
loadTestImplementation.extendsFrom testImplementation
}

dependencies {
... various deps ...
loadTestImplementation "org.jsmart:zerocode-tdd:1.3.+"
}

task loadTest(type: Test, group: "verification") {
include '**/*LoadTest.class'
testClassesDirs = sourceSets.loadTest.output.classesDirs
classpath = sourceSets.loadTest.runtimeClasspath
outputs.upToDateWhen { false }

systemProperty 'zerocode.junit', 'gen-smart-charts-csv-reports'
}
~~~

Here is the load test class:

~~~
@LoadWith("load-config.properties")
@TestMappings({
@TestMapping(testClass = CounterRecorderTest.class, testMethod = "whenRecordIsCalledThenCounterIsIncremented"),
@TestMapping(testClass = DistributionSummaryRecorderTest.class, testMethod = "whenRecordIsCalledThenTimingsAreRecorded"),
@TestMapping(testClass = TimerRecorderTest.class, testMethod = "whenRecordIsCalledThenTimingsAreRecorded")})
@RunWith(ZeroCodeMultiLoadRunner.class)
public class RecorderLoadTest {
}
~~~

Start with the Gradle loadTest task and its `zerocode.junit` system property, then trace how `RecorderLoadTest` invokes `ZeroCodeMultiLoadRunner` with `load-config.properties`. Check the load-test resources and the report-generation entry point to determine why the expected CSV files are absent while logs and JUnit results exist. Done means the load test produces the CSV reports in the intended target folder.
