deck.gl: assertion failed

[zilingziling]

hi ，when I try to change map's center，I got an error "Error in callback for watcher "viewState": "Error: deck.gl: assertion failed." Do you know why this is happening ？

here is my code :

watch: { mapCenter(val) { setTimeout(() => { this.viewState = { ...this.viewState, latitude: val[1], longitude: val[0], transitionDuration: 1000, };

   });
},

},

If you have time, could you please help me with this? I would really appreciate it.
