Using uni simple router, dynamically pass parameters typeerror: cannot convert undefined or null to object

Previous code ：

					this.$Router.push({
    
						path: `/pages/workbench/index/index`,
						query: {
    
							list: list,
							data_url: list.data_url
						}
					})
				}

The modified code ：

	/*  Be careful ： Use router It's pit. , You can solve this problem in two ways ： 1.  You can query It uses encodeURIComponent(JSON.stringify(list)) To transmit parameters  2.  You can use vuex To transmit parameters , It can also realize dynamic parameter transfer  this.$store.commit('xxx', list) */
					this.$Router.push({
    
						path: `/pages/workbench/index/index`,
						query: {
    
							list: encodeURIComponent(JSON.stringify(list)),
							data_url: list.data_url
						}
					})

 I added it here encodeURIComponent(JSON.stringify(list)),

Data received

/*  Be careful ： Use router It's pit. , You can solve this problem in two ways ： 1.  Scheme 1 （ recommend ）： You can query It uses encodeURIComponent(JSON.stringify(list)) To transmit parameters  2.

			//  Option two 
			// console.log(this.$store.state.limit)
			// this.name = this.$store.state.limit.name == 'undefined' ? this.$store.state.limit.url : this.$store.state.limit.name
			// this.data_url = this.$Route.query.data_url
			// uni.setNavigationBarTitle({
    
			// title: this.$store.state.limit.title
			// });
			
			//  Scheme 1 
			this.name = this.$Route.query.list.name == 'undefined' ? this.$Route.query.list.url : this.$Route.query.list.name
			this.data_url = this.$Route.query.data_url
			uni.setNavigationBarTitle({
    
				title: this.$Route.query.list.title
			});
