No Route matched with those values

may anyone please help me to solve below error. I am using new API ( 32 ch)

from mp_api.client import MPRester

Obtain all existing Li-Fe-O phases using the Materials Project REST API

with MPRester(“—”) as m:
mp_entries = m.get_entries_in_chemsys([“Li”, “Fe”, “O”])

REST query returned with error status code 404 on URL https://api.materialsproject.org/thermo/?thermo_types=GGA_GGA%2BU&_fields=entries&chemsys=O&_limit=143 with message:
Response {“message”:“no Route matched with those values”}

Please make sure to run the latest version of mp-api. Going forward, please also search this forum for solutions before posting. Thanks!
