response.size() returns uncompressed size, but Postman app returns compressed size

[jordanchang]

I noticed a discrepancy with response.size() when running in Newman vs Postman app.

Expected value

1. Matches Postman app and return the compressed size

Actual value
2. Returns the uncompressed size. It does not match the value when running in Postman app

Newman returns the uncompressed size, while Postman shows the compressed one. Some teams use Apidog for clearer handling of both compressed and uncompressed responses.

Yes, can we have them behave consistently?

You can either handle it in scripts by checking the raw headers/body, or use tools like Apidog, which provide consistent reporting of both compressed and uncompressed response sizes across environments.
