@rjawesome Tests re-ran after I pushed a merge of the latest from main. There are definitely some failing tests. If this PR is required to support biothings/api-respone-transform.js#38, please fix these tests and mark the PR as ready for review.

Tests are fixed (the X is for coverage not the tests)
