@kidunot89 the phpstan error you just got is because the .neon file isn't correctly pointing to the wp-graphql-jwt-authentication plugin. Could be that the env step doesn't include it (I assumed it did because I saw there were wpunit tests) or just that I got the path wrong.

@justlevine I just redirected the file to used the plugins in the WP installation at /local/public created running composer installTestEnv.
