The provided code seems generally well-structured and follows best practices for Vue.js development. However, there are a few adjustments that can be made:

1. Button Disable State Management: It's important to manage the button disable state more explicitly to ensure it reflects the correct status at all times.

2. Error Handling in finally Block: The finally block should also reset loading even when there is an error during submission.

Here is the improved version of the code:

In this revised version:

• An additional function canSubmit() has been introduced to determine whether the form is ready to be submitted based on conditions like selectedNodes.length > 0.
• disabled is set only when canSubmit() returns false, ensuring that users cannot trigger the import button unless the necessary data is selected.
• Both disabled and loading have been correctly managed throughout the submit function, including in the finally block.
