Good day, Nhan. The error you’re experiencing is likely caused by a minor browser glitch or a build-up of cached data.
Before proceeding, could you let us know which part of your QuickBooks account this error is appearing in? Having more information will help us better understand the issue and provide a more accurate resolution.
With that said, I recommend refreshing your browser’s data by logging out of your QuickBooks Online (QBO) account and then logging back in. Doing so will refresh your account and can resolve minor glitches that may be causing the error.
