Could not find lane 'ios debug'. Available lanes: ios beta - fastlane

Question

when I added a new fastlane like this in Fastfile:
default_platform(:ios)
platform :ios do
desc "Push a new beta build to pgy"
before_all do
ENV["CACHE_GIT_URL"] = ENV["GIT_URL"]
end
lane :debug do
xcode_select "/Applications/Xcode.app"
match(
type: "adhoc"
)
build_app(
workspace: "Runner.xcworkspace",
scheme: "Runner",
export_method: "ad-hoc",
skip_archive: true
)
pgyer(
api_key: ENV['PGY_API_KEY'],
user_key: ENV['PGY_USER_KEY']
)
end
lane :beta do
xcode_select "/Applications/Xcode_12.4.app"
if is_ci
create_keychain(
name: ENV['MATCH_KEYCHAIN_NAME'],
password: ENV["MATCH_KEYCHAIN_PASSWORD"],
default_keychain: true,
unlock: true,
timeout: 3600,
lock_when_sleeps: false
)
end
match(
app_identifier: ENV["APP_IDENTIFIER"],
git_url: ENV["GIT_URL"],
type: "adhoc",
readonly: is_ci,
keychain_name: ENV['MATCH_KEYCHAIN_NAME'],
keychain_password: ENV["MATCH_KEYCHAIN_PASSWORD"]
)
build_app(
workspace: "Runner.xcworkspace",
scheme: "Runner",
export_method: "ad-hoc",
skip_archive: true
)
pgyer(
api_key: ENV['PGY_API_KEY'],
user_key: ENV['PGY_USER_KEY']
)
end
end
I added a new lane called debug, but when I run the command:
bundle exec fastlane debug
shows error:
$ bundle exec fastlane debug ‹ruby-2.7.2›
