Summary

• The issue was caused by how SparseBooleanArray works. Previously, the logic incorrectly included attributes because missing keys were treated the same as keys with a false value. By providing a default value, the filtering now correctly includes attributes only when they are allowed and excludes them only when the configuration explicitly marks them as false. This aligns the behaviour with the intended filtering logic.

Testing Plan

• Was this tested locally? If not, explain why.
• Tested this using the sample app and ran the unit tests.
