We have been using the QuickBooks API for several years, but recently (over the past two days), we've encountered a problem where we're unable to fetch certain items that are available in QuickBooks Online (QBO). Additionally, when trying to add these items through the API, we're receiving errors indicating that duplicate names exist, which prevents us from adding new product items. This issue is causing problems for some of our clients who are unable to add invoices via the API. We need assistance in resolving this issue.
