I'm aware of this, but I think that since the loading has been updated, the page’s loading status should also be updated accordingly. As for the error about the doesn't have length property, it can be prompted separately in the console.

Or am I understanding that you mean, since Vue has already thrown an error, it will not update the page anymore?

Since the current component has thrown an error, it will no longer update this component. Other components on the page will update normally
