Add test cases for recursion #1242
Description
Description
The existing tests in library/src/helpers/__tests__/schema.test.ts cover basic transformations (strings, numbers, arrays, objects) but do not test various kinds of recursions which can occur such as
- True circular references
- Same object in different branches
- Deep nesting without circularity
- Other edge cases
Expected result
The changes made in #1101 and #1241 should have appropriate test cases for them.
