undefined array keys in php 8.1

[eliargon]

Trying to run an f3 app (using version 3.8.0) with php 8.16 I am getting Internal Server Error Undefined array key for.... ERROR, CLI, VERB and other $hive[...] keys. Using the suggestion of checking for isset($hove['key']) first, eliminate the first occurrence but then stop on the next one.

Any ideas on how to eliminate this?
