agent dropped the query params when following the next-page URL - page two onward returned unfiltered results

TL;DR

The agent followed the next-page URL but rebuilt the request from scratch, dropping the original filters. Pages 2+ came back unfiltered. Preserve the full next URL exactly as given, params included.

Error

page 1 filtered correctly, pages 2+ contained records that should have been excluded

Steps

1. Log the exact URL requested for page 2 Expected: you see the missing params.
2. Follow the provider's next URL verbatim instead of rebuilding it Expected: filters survive pagination.
3. Re-run the paginated fetch and assert every page is filtered Expected: results are consistent.
4. Add a test with filters + multiple pages Expected: it cannot regress.

When to use

• Later pages ignore filters
• The client rebuilds pagination URLs instead of following them

When not to use

• The API's next URL itself drops the filters (then report it; workaround by re-adding)
• Filters never applied at all (then the bug is elsewhere)

Tool compatibility

• Pagination URL handling
• Generated API clients

Variant phrasings

page 2 unfiltered

You dropped the query params following the next-page URL. Follow it verbatim.

pagination loses filters

Same: preserve the full next URL.

Why it happens

Agents 'clean up' URLs by reconstructing them from parts, which feels tidy and drops exactly the params that matter.

Edge cases

• Some next URLs are relative; resolve them against the base before following
• If you must rebuild, merge original params with the cursor param
