php 8.1 oEmbed warning

Hi,

Small warning started with php 8.1, when WordPress tries to handle an oEmbed request:

PHP Warning: Attempt to read property “post_type” on null in /plugins/events-manager/classes/em-location-post.php on line 76

It seems that the code on line 76 always assumes a location post_type exists. Adding some isset() checks on post and post_type before reading seems to fix it.

EM: 7.1.7, PHP: 8.1, WordPress: 6.8.2

Best,
