The nikic/php-parser throws "trailing comma is not allowed" but I use PHP 7.3.22 which allows trailing comma…

[mattkomarnicki]

I wanted to use beyondcode/laravel-er-diagram-generator to generate diagram of my Lumen app. Installation went smoothly with no issues.

When I run php aritsan generate:erd I get:

$ php artisan generate:erd

In Php7.php line 1170:

A trailing comma is not allowed here on line 71

I started investigation and I've found that this links to one of my files where indeed I have a comma after the last argument of a method, but the case is that I use both locally and in production PHP in version 7.3.22 and allowance of trailing comma was implemented in 7.3.

So what is the issue? When I remove that comma from the last argument, then the diagram is generated with no issues. How can I fix this without being forced do write older PHP syntax?

Is it something with diagram package or nikic/php-parser, which is a dependency of the diagram package?

Also in my Lumen composer.json I do have indeed different version of PHP:

"require": {
    "php": ">=7.1.3",

but does this matter?

Version that is physically used is:

$ php -v
