tiene un error de cara en la visualización completa del calendario. Recibí JSON de un servlet en los siguientes formatos.

Tipo1: [["title2","2021-09-10","2021-09-10"],["title2","2021-09-10","2021-09-10"],

Tipo2: [["title2","2021-09-10","2021-09-10"],["title2","2021-09-10","2021-09-10"]]

Este es el error que veo en la consola de Google Chrome:
