There was an issue displaying the page. Possible reasons include: you haven't accepted the GNoME terms of use; or the material with mpid: mp-767093 does not exist in our database

How to solve this? I’m on the page of XAS, once I click one of data, this error occurs while I expected material details.

Yes, that’s a known issue unfortunately. Some of the mp-ids in the XAS section haven’t been updated to point to the correct material. You can use the mp-api client to query the task_ids field in the summary collection and figure out what the new material id is. mp-767093 belongs to mp-753523 now, for instance. HTH.
