Whitespace or Encoding Differences: There may be invisible differences (e.g., whitespace, newline, UTF-8 BOM).
Type Differences: One value may be a boolean (true) and the other an integer (1). However, in your output both are 1.
Test Assertion Logic: The test may be using a strict comparison (e.g., string equality), which can fail for reasons above.

How to Debug

Add Debug Output: Print the raw bytes or use a hex dump of both strings in your test to spot differences.
Compare as Data Structures: Instead of comparing JSON strings, parse them into objects and compare those.
Check Test Assertion: Review the assertion code at or around tests/dm-tests.rs:188 for how the comparison is performed.

Recommendation

Inspect the test logic and add logging to print the exact bytes being compared.
If possible, switch the test to compare deserialized structures instead of raw JSON strings.
(Optional) Use a JSON diff tool to check for hidden differences.
