Hard to tell without seeing some of the project structure and/or files. Some thoughts, though:

• you are scanning . - i.e. the project root. That might include the vendor folder and probably other folders/files that are not relevant and might break things. Reducing this to the folders that do actually contain code with annotations might be enough (you can specify multiple files/folder)
• The code in question does a xxx_exists() check. Failing this usually means there is no (or incorrect) autoloading set up

Appreciate your reply!

I think the first point was my issue. I changed the path to point to src/Controller (I have a CakePHP project) and it went through fine.
