how to run instrumentation tests using fastlane in emulator?

The problem that I face is I could'n run the espresso tests using fastlane, what I want to do is run the tests in an emulator by fastlane plugin

I used automated_test_emulator_run plugin of fastlane, I follow the steps in this article https://medium.com/pink-room-club/android-continuous-integration-using-fastlane-and-circleci-2-0-part-i-7204e2e7b8b

for now I just want to run the tests locally so when I run the following

bundle exec fastlane instrumentation_tests

it fails with error: No such file or directory - /tools/bin/avdmanager

here my lane in fastFile

default_platform(:android)

platform :android do
desc "Runs all the tests"
lane :test do
gradle(task: "test")
end

#for increment the version code
android_get_version_code(
gradle_file: "app/build.gradle" # optional
)

android_set_version_code(
gradle_file: "app/build.gradle" # optional
)

desc "Run instrumentation tests"
lane :instrumentation_tests do
automated_test_emulator_run(
AVD_setup_path: "fastlane/AVD_setup.json",
AVD_recreate_new: false,
AVD_clean_after: false,
gradle_task: "connectedDebugAndroidTest")
end
end

And this my AVD_setup.json

{
"avd_list": [
  {
    "avd_name": "Pixel_2_API_Test",

    "create_avd_package": "system-images;android-28;google_apis_playstore;x86",
    "create_avd_device": "Pixel 2",
    "create_avd_tag": "google_apis_playstore",
    "create_avd_abi": "x86",
    "create_avd_additional_options": "",
    "create_avd_hardware_config_filepath": "",

    "launch_avd_port": "",
    "launch_avd_snapshot_filepath": "",
    "launch_avd_launch_binary_name": "emulator",
    "launch_avd_additional_options": "-skin 1080x1920 -gpu on"
  }
]
}

here is a part of the output and the error I got

I don't know what should I do? what I missed? the error mention that this might be due to fastlane's directory handling so I went to the link but didn't understand what to do?! I am using updated fastlane and plugins, please help me and thanks in advance
