echo (new InvalidArgumentType(2, 'string', null))->getMessage();

Output for git.master, git.master_jit, rfc.property-hooks: Argument 1 value {} should be string but is Foo. Argument 2 value [1,2,3,4,5 ... ] should be string but is array. Argument 3 value 123 should be string but is integer. Argument 2 value null should be string but is NULL.
