Fix TypeError in is_auto_completion_input for Elements Without Class Attribute

This pull request fixes a TypeError that occurs in the is_auto_completion_input method within the SkyvernElement class. The error is triggered when attempting to perform a substring check on a None value returned from elements without a class attribute.

Issue

• Type: Bug Fix
• Issue ID: #1250

Problem

When processing DOM elements without a class attribute, the following error occurs:

TypeError: argument of type 'NoneType' is not iterable

Changes Made

• Added explicit None check before performing string operations
• Improved error handling for elements without class attributes
• Maintained original functionality for autocomplete detection
• Added defensive programming approach to prevent similar issues

Testing

• Verified fix works with elements that:
  • Have no class attribute
  • Have empty class attribute
  • Have valid class attribute
• Confirmed autocomplete detection still works as expected

  The change correctly adds a None check to prevent a TypeError when class_name is None. This is a good defensive programming practice.

  The change made in the PR is correct and aligns with the description provided. The explicit check for None before performing the substring operation prevents the TypeError. The rest of the code in the method is consistent with the intended functionality.
