Hi there, manjunath-hubilo. I want to ensure you'll get directed to the right support.
May I know if you're a developer? If you're one, you can visit our Intuit Developer Community. This is where developers engage with others to discuss programming or API concerns.
Otherwise, if you're a QuickBooks Online user, I'd suggest reaching out to third-party app support. They can verify why you're getting an error and configure to ensure information is syncing properly.
You might also want to check our QuickBooks Online learning guides. This includes help articles, video tutorials, and others to get a better grasp of the product.
The Community has your back should you need assistance with any QuickBooks concerns. Have a great day.
