Having clustered collections will use object id as record id. When comparing keystrings in scanIndexForDuplicates, we cannot assume that RecordId will be a long. We will need to update the comparison to something like this.

Remove TODO in buildscripts/resmokeconfig/suites/clustered_collection_passthrough.yml to include collmod_convert_to_unique_violations_size_limit.js in the clustered collection passthrough.
