I created a .neon file from the documentation.

https://phpstan.org/user-guide/discovering-symbols

I put the .neon file in the project root folder where I am running the phpstan command from. I added these lines.

parameters:
   level: 0
   scanDirectories:
          - src
          - library
          - interface

This is the command that I am executing from the CLI

php vendor/bin/phpstan analyse -c phpstan.neon interface/patient_file/report

I have copied and pasted the example from the documentation to get the format corrected and still get the error message.
