Comment (by hbhalodia):

 > I agree with @dd32 that throwing a warning in this instance is correct.
 The error can only be hit when developers call the function incorrectly.

 > I think the fix for this is to improve the documentation for the
 function to note which items are required and which items are optional in
 the $userdata docblock.

 While I understand the perspective, I respectfully disagree. Accessing an
 array key without first verifying its existence is considered poor
 practice, as it can lead to unnecessary warnings. Although these warnings
 may be suppressed on production environments and remain invisible to end
 users, it is still best practice to implement proper checks before
 accessing array elements. This approach ensures more robust and
 maintainable code, and prevents avoidable issues from arising in different
 environments.

 Even if the docblock specifies that a particular key is required, it is
 still prudent for the consuming code to verify the presence of that key.
 If the key is missing, the code should either initialize it accordingly or
 throw an appropriate error—both approaches are acceptable depending on the
 context. In our current implementation, however, the necessary isset or
 empty check is missing, which ideally should be included to ensure the
 code’s reliability and robustness.
