Problem

get_one_player in app/routers_v2/players.py returned a CSV response containing only the header row — player data was never included.

Root Cause

return_val = DataFrame(data_list).to_csv(header=False, index=False) was called on line 625 when data_list contained only the header list. The player data row was appended to data_list on line 626 — after the CSV was already computed.

Solution

Moved the to_csv() call to after data_list.append(player_row). Single-line swap, no logic changes.

Files Changed

• app/routers_v2/players.py (~line 625-651)
