EF Core is throwing DbUpdateConcurrencyException, but only on the production database (MySQL)

public async Task Execute(IJobExecutionContext context)
{
    // databaseFactory is injected as a dependency (IDbContextFactory<AppDatabase>)
    await using var database = await databaseFactory.CreateDbContextAsync();

    int page = 0;
    while(true)
    {
        List<WarehouseEntry> dbItems = warehouse.QueryPage(page, 1000); // Retrieves 1000 entries from somewhere
        if(dbItems.Count == 0) 
            break;

        database.ProductWarehouseCache.AddRange(dbItems.Select(p => new CachedWarehouseProduct {
            Sku = p.Name,
            Barcode = p.Barcode,
            Stock = p.Stock,
            Price = p.Price
        }));

        await database.SaveChangesAsync(); // <---- DbUpdateConcurrencyException is thrown here
        page++;
    }
}
