Null-safe operator is php 8.0+ only

[ptdev]

Hey,

The change introduced here appears to be using the null-safe operator that was apparently only introduced with php 8 while the documentation still states F3 minimum requirement is php5.6+

Updating a project on latest php 7.4 for example breaks with the following error

PHP Parse error: syntax error, unexpected '->' (T_OBJECT_OPERATOR)

Cheers 👍
