When building Magento, a lot seems to fail when expected to work. One computer may succeed in building, while another throws a few errors. This may be because of the difference in PHP, but the ones I have tested had some very similar setups (Ubuntu 16.04, PHP 7.2, same SQL version, all set up by me with the same processes)
Now when developing all my compilations succeed. But when pushing the composer file run the building steps on another PC, e.g. Pull > setup:upgrade > setup:di:compile.. the compilation often fails.
Most of these are pretty easily fixed and (maybe) a result of my project setup with modules. However, others are hard to debug as far as I can see.
Currently, I am getting the error cited below. (note the required type array, actual type array)
I am not sure how to proceed. Removing vendor directories or cleaning cache does not help. Where can I start debugging (as this seems to be a core-Magento error and the error does not tell me anything)? I am running a very similar project that has almost all the same dependencies which does compile.
