Uncaught (in promise)和Uncaught (in promise) TypeError: Cannot read properties of undefined (readin

As long as you add .catch((e) => {}) at the end, you will not get an error.

const queGetdata = (params, context) => {
	
	return new Promise((resolve, reject) => {
		appVue.$http.post(appVue.$apis.getdata,
			{
			  gcode: 'QUERY_CUSTBILL'
			}, {
				isAutoLoading: false, //是否展示loading
			}).then(resp => {
				console.log("触发进来了222222")
			let data = resp.responseBody.paramdata; 
			console.log("触发进来了"+JSON.stringify(data[0]))
			
			// commit必须放在后面，不然会报错“Uncaught (in promise) TypeError: Cannot read properties of undefined (readin”
			context.commit("setCustbill", JSON.parse(JSON.stringify(data[0])))
			console.log("触发data[0]"+JSON.stringify(data[0]))
			resolve(data[0])
			
		}).catch(error => {
			reject(error)  // 这里报error写进去就不会报错，注意注意 Uncaught (in promise)
		});
	})
}

 

 To solve this problem, you need to resolve() and commit() otherwise an error will be reported. Note: the order.

const queGetdata = (params, context) => {
	
	return new Promise((resolve, reject) => {
		appVue.$http.post(appVue.$apis.getdata,
			{
			  gcode: 'QUERY_CUSTBILL'
			}, {
				isAutoLoading: false, //是否展示loading
			}).then(resp => {
				console.log("触发进来了222222")
			let data = resp.responseBody.paramdata; 
			console.log("触发进来了"+JSON.stringify(data[0]))
			resolve(data[0])
			// commit必须放在后面，不然会报错“Uncaught (in promise) TypeError: Cannot read properties of undefined (readin”
			context.commit("setCustbill", JSON.parse(JSON.stringify(data[0])))
			console.log("触发data[0]"+JSON.stringify(data[0]))
			
			
		}).catch(error => {
			reject(error)
		});
	})
}
