Cocoapods Ionic Pro

Recently, the cordova-plugin-googlemaps started using cocoapods. I have found the article that is supposed to be a solution to the matter:

However, I get this error:

[03:02:19]: Error setting value '/Users/ionic/builds/project-0/platforms/ios/PROJECT.xcodeproj' for option 'path'
[03:02:19]: You passed invalid parameters to 'update_project_codesigning'.
[03:02:19]: Check out the error below and available options by running `fastlane action update_project_codesigning`

Does anybody know how to package a build in Ionic Pro that requires cocoapods? Will I have to revert the googlemaps plugin to an older version?
