The returned value from readQuery should not be modified in place, it should be copied. See last paragraph of readQuery documentation at https://www.apollographql.com/docs/react/caching/cache-interaction/:

Do not modify the return value of readQuery. The same object might be returned to multiple components. To update data in the cache, instead create a replacement object and pass it to writeQuery.
