I found that if I alter the generated build.gradle file to better match what is shown here, that I can get the expected response.

Specifically, changing the runFunction task from

args(
            '--target', 'io.micronaut.gcp.function.http.HttpFunction',
            '--classpath', (configurations.runtimeClasspath + sourceSets.main.output).asPath,
            '--port', 8080
    )

to

args(
            '--target', 'io.micronaut.gcp.function.http.HttpFunction',
            '--port', 8080
    )
    doFirst {
        args('--classpath', files(configurations.runtimeClasspath, sourceSets.main.output).asPath)
    }
