[Vue warn]: Error in onLoad hook: "TypeError: this.setData is not a function"

This error message is related to a problem in a Vue component's onLoad hook. Specifically, it suggests that the setData method is not defined or accessible within the current context.

The setData method is typically used in the context of a Vue instance or component to update the data that is being used to render the component. It is possible that there is a problem with the way that the component is structured or initialized that is preventing the setData method from being properly defined or accessed.

To troubleshoot this issue, you may want to review the code for the component and ensure that it is properly structured and initialized. You may also want to check for any other errors or issues that could be causing problems with the component's operation. Additionally, you may want to consult the Vue documentation or seek help from the Vue community to find additional resources and solutions for this issue.
