Estoy trabajando en una aplicación SpringMVC. Solicité algunos datos de la base de datos utilizando una llamada ajax. Los datos regresaron como objeto json. Ahora tengo que enviar estos datos de vuelta al servidor para su procesamiento y volver al formulario.

Sin embargo estoy recibiendo un error en el navegadorEl servidor encontró un error interno que le impidió cumplir con esta solicitud. Al investigar los registros de error vi esto:
