I'm working on a Drupal 10.5.1 site that's showing me a warning message: Warning: Undefined array key "#submit_button" in Drupal\Core\Render\Element\Button::preRenderButton() (line 92 of core/lib/Drupal/Core/Render/Element/Button.php).
This looks like it's related to something in the Core innards of Drupal into which I'm not comfortable poking my proverbial finger.
Has anyone else been seeing this message?
Any idea of what I should do - besides ignoring it?
We recently monitored our website through a monitoring trace tool and found that huge number of redis call method error, php deprecated warnings , and module execution delays.
Anyone else facing this? If yes any short term resolution? Because the exceptions coming are in millions in every 24 hours.
