mp_api.client.core.client.MPRestError: REST query returned with error status code 404

I am coming across “mp_api.client.core.client.MPRestError: REST query returned with error status code 404” when running basic data querying API. See the detailed error message in the attached figure. Does anyone know why this error happens and how to resolve it? Thanks!

Please try updating to the latest mp-api client version.

Hi! I’m having the same issue.
I installed the latest mp-api client and restarted the kernel, but still the problem persists.
I can access material properties through pymatgen, but MPRester gives the 404 error as above.
Any tips? Thanks!!
