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.
