JSON-THROW-ON-ERROR

[benetel]

Hi,
I use Webtrees 2.0.16
As I activate the the pedigree chart custom module (v 1.2.5) and try to display it on my webtrees pages, the resuls is an error message :

"use of undefined constant JSON-THROW-ON-ERROR,
as shown in the image

It seems that this error is due to a version of PHP lower than 7.3. I advise you to update your PHP installation in order to fix this problem.

Nevertheless, it's best practice to declare constants as well as classes, eg

use const JSON_THROW_ON_ERROR;

I created a new release for PHP 7.1 to remove this dependency. Nevertheless you should upgrade your PHP version as 7.1 is outdated.
