/approval request for backport. Updated getService to check whether getProvider returns null when checking for preferred providers, continuing the loop if so. Added NullPreferredList test.

Risk: Low. Tip change was merged in May 2024 and adds conditional statement to catch exception case, otherwise preserving functionality. Further, new test explicitly confirms altered functionality.

Testing:

• GHA Sanity Checks
• Tier 1 and 2 tests locally
