Undefined array key error relating to relationship field - EE 7.4.1 #4079
Description
Description of the problem
Getting a block of warnings errors on multiple pages on a site newly updated from EE4 to EE7.4.1
Site is running php 8.0.
Warnings appear to relate to a missing index being accessed by the entry method in Parser.php. Am guessing the remaining warnings are cascaded from this issue. Have done limited poking around and a value is passed as $id in this line (39) but the array $this->_entries does not contain a key with this value.
return $this->_entries[$id];
