When I tried to use it in a query, everything looked fine in the code but Hydrogen complained:

I also couldn't find this field in older/newer versions of the web docs so it might be a leftover from a long time ago?

Expected Behavior

API types don't include outdated/missing fields.

Actual Behavior

API types include a not existing hasMultipleFulfillments field.

Start at packages/hydrogen-react/src/customer-account-api-types.d.ts around lines 5151-5152 and compare the declared Order fields with the current Customer Account API documentation or GraphiQL schema. Remove or correct the outdated field declaration, then verify that the generated types no longer expose hasMultipleFulfillments and that the relevant package checks pass.
