Hello,

without submitting the form, Jsonforms displays the default error message, I need to display an error message when I submit a form; if you could please advise me on how to do this and, if you can, provide an example or link.

Hi @gowthaman-murugan,

This use case is covered via our `validationMode` support. See [here](https://jsonforms.io/docs/validation#validationmode) for the documentation.
