ios - FaSTLane:测试 SPM 包时为 "no implicit conversion of nil into String"

Question

我正在尝试使用 FaSTLane 在 SPM 包上运行一些测试，但我收到了一个相当模糊的错误

no implicit conversion of nil into String

我的 faSTLane 车道是这样的:

lane tests_ios do
    TEST_PACKAGE_PATHS.each { |package_path|
        scan(
            workspace: WORKSPACE_NAME,
            package_path: package_path,
            devices: TEST_DEVICES_IOS,
            code_coverage: true
        )
    }
end

我猜缺少一个参数？除了没有迹象表明到底是哪一个。

如何解决？或者至少如何获得更详细的错误消息以指明正确的方向？

这是终端的完整输出:
