Fastlane finished with errors - Match - no error message

Question

I updated fastlane to the newest version ( 2.162.0)

Now when I try to run fastlane buildApp, it errors out and hangs forever with the only output:

fastlane finished with errors

Terminal Output:

% fastlane buildApp

However, if I run the match command directly into my terminal, it works fine without a problem.

fastlane match appstore --force=true --app_identifier=com.MyCompany.AppName

Fastfile (Stripped down to reproduce the problem)

default_platform(:ios)
platform :ios do
  lane :buildApp do
    match(force: "true", type:"appstore", app_identifier: "com.MyCompany.AppName")
  end
end

So my question is why does this work when typed directly in the console but no longer works via my Fastfile?

Answer 1

After hours of trying different things, I finally ran:

sudo gem clean

And now it works as expected -_-

Putting this here in case it saves anyone else the frustration!
