Hello, info1082. 

Thank you for bringing this up in the Community. I've checked with my resources and verify with the engineering team, the investigation Error:"message":System is unable to process your request",code":-30006,"detail":"System is unable to process your request" has been resolved. If you are still experiencing this unexpected behavior, let's see if this is a browser issue or not, let's try refreshing your browser by clicking the Reload icon or pressing F5 on your keyboard. If the same things happen, we can continue following the recommended troubleshooting steps above.  

To start, log into your QuickBooks account using a private browser/incognito. Here's how: 

• Press Ctrl+ Shift + N keys on your keyboard (Google Chrome).
• Press Ctrl+ Shift + P keys on your keyboard (Firefox or Internet Explorer).
• Press Control+ Option + P keys on your keyboard (Safari).   

If the private browsing session works, it means that you need to clear the browser's cache so the system can start fresh. You can also do this task on other supported, up-to-date browsers. Clearing the cache will refresh the system, and you'll be able to work with clean trash.       

In case you have other questions about QuickBooks, please post them here. We are available to answer them right away. Stay safe!
