Getting error 400 from updating a cell by google sheetsAPI - node.js

I am trying to update a cell in a spreadsheet through Google spreadsheet API.
Currently, I'm having the following code snippet:
sheetsApi.spreadsheets.values.update({
spreadsheetId: spreadsheetId,
range:"Sheet1!P1",
valueInputOption:'USER_ENTERED'},
{"data":{"values":[[5]],
'majorDimension':"ROWS"}
}
)
And it gives the following error:
{
"error": {
"code": 400,
"message": "Invalid JSON payload received. Unknown name \"data\" at 'data': Cannot find field.",
"status": "INVALID_ARGUMENT",
"details": [
{
"#type": "type.googleapis.com/google.rpc.BadRequest",
"fieldViolations": [
{
"field": "data",
"description": "Invalid JSON payload received. Unknown name \"data\" at 'data': Cannot find field."
}
]
}
]
}
}
Could someone give me some help with this please?
Thank you very much!
Since I am only testing this 'update' function, the script is very simple, as the following:
function main() {
const credentials = {
accessToken: '',

};
const spreadsheetId = ''
var sheetsApi = GoogleApis.createSheetsService(credentials);
sheetsApi.spreadsheets.values.update({
spreadsheetId: spreadsheetId,
range: "Sheet1!P1",
valueInputOption: "USER_ENTERED",
resource: {
values: [[5]],
majorDimension: "ROWS"
}

Array push gives empty result node js

I am creating an API for listing trip data with image and pdf base url,
All things are working fine but I can not access the last result array data_to_send out of for loop.

this is because of the asynchronous behavior of NodeJs, so you have to plan things accordingly i.e
console.log(1)
db.select(
"trip",
"*",
`driver_id = '${req.params.userId}'`,
async (data) => {
console.log(2)
})
console.log(3)
The output of the above code would be 1 then 3 and then 2 and this is how NodeJs works it does not wait for I/O calls i.e DB query in your case.
Please check how promises work in NodeJs for more details.
Here is how you can accomplish your task:
const challanList = (userData) => {
return new Promise((resolve, reject) => {
const data_to_send = [];
db.select("trip", "*", `driver_id = '${req.params.userId}'`, data => {
for (let i = 0; i < data.data.length; i++) {
const site_source = data.data[i].site_from;
const site_destination = data.data[i].site_to;
db.select("site", "*", `id in ('${site_source}','${site_destination}')`, data_site => {
data.data[i].site_from = data_site.data[0].name;
data.data[i].site_to = data_site.data[1].name;
if (data.data[i].truck_challan_pdf != "") {
data.data[i].truck_challan_pdf = base_url + "truckchallan/" + data.data[i].truck_challan_pdf;
}
if (data.data[i].driver_challan_pdf != "") {
data.data[i].driver_challan_pdf = base_url + "driverchallan/" + data.data[i].driver_challan_pdf;
}
if (data.data[i].preparer_img != "") {
data.data[i].preparer_img = base_url + data.data[i].preparer_img;
}
if (data.data[i].driver_img != "") {
data.data[i].driver_img = base_url + data.data[i].driver_img;
}
data_to_send.push(data.data);
// console.log(data_to_send); // working
});
}
resolve(data_to_send);
});
});
};
app.get("/getChallanList/:userId/:role", async (req, res) => {
const userData = req.params;
const challanListResult =await challanList(userData);
console.log(challanListResult);
resp.json(challanListResult);
});
Without knowing what database or ORM you are using it is difficult to answer, but my suspicion is that db.select is an asynchronous method, i.e. it is returning a Promise. If so, the second console log is still seeing the "old" data_to_send.
Try adding an await in front of the first db.select call. (Don't forget the async in front of the callback in second argument of app.get.
Your database is asynchronous so console.log(data_to_send) gets called before the query finished executing. Try adding async before (req, res) in line 1 then await before db.select.
This works for me
app.get("/getChallanList/:userId/:role", async (req, res) => {
const userData = req.params;
let site_source = "";
let site_destination = "";
var site_from_name = "";
const data_to_send = [];
if (userData.role == "D") {
const data = await db.query(
`SELECT * FROM trip WHERE driver_id = '${req.params.userId}'`
);
// console.log(data.length);
// const data_to_send_ = [];
for (let i = 0; i < data.length; i++) {
site_source = data[i].site_from;
site_destination = data[i].site_to;
// cons
const site_data = await db.query(
`SELECT * FROM site WHERE id in ('${site_source}','${site_destination}')`
);
// console.log(site_data);
db.select(
"site",
"*",
`id in ('${site_source}','${site_destination}')`,
(data_site) => {
data[i].site_from = data_site.data[0].name;
data[i].site_to = data_site.data[1].name;
if (data[i].truck_challan_pdf != "") {
data[i].truck_challan_pdf =
base_url + "truckchallan/" + data[i].truck_challan_pdf;
}
if (data[i].driver_challan_pdf != "") {
data[i].driver_challan_pdf =
base_url + "driverchallan/" + data[i].driver_challan_pdf;
}
if (data[i].preparer_img != "") {
data[i].preparer_img = base_url + data[i].preparer_img;
}
if (data[i].driver_img != "") {
data[i].driver_img = base_url + data[i].driver_img;
}
data_to_send.push(data);
// console.log(data.data);
// console.log(data_to_send); // working
}
);
// data_to_send_.push(data_to_send);
}
// console.log(data_to_send);
// console.log(data_to_send);
res.send({ success: 1, data: data, message: "" });

How can write a column in tsv file using node js?

I have to write a json response in a column of tsv file how can I do that?
I am using the following code. Please find me a solution? I have to check it but its not working.
//npm init -y gen package.json file
var unProcessedItems = [];
var data = loadData('./Alabama_Pre_Final.tsv');
async function X(i) {
if (data[i] && data[i][7]) {
console.log(data[i][7]);
function address(address_details) {
request({
url: 'https://us-extract.api.smartystreets.com/?auth-id=xxx&auth-token=xxx',
method: 'POST',
headers: {
'content-type': 'application/json'
},
body: address_details,
},
(error, response, body) => {
if (!error && response.statusCode == 200) {
var res = JSON.parse(body);
let objectArray = [];
if (res.addresses[0].verified) {
objectArray.push(res.addresses[0].api_output[0].delivery_line_1, res.addresses[0].api_output[0].last_line, res.addresses[0].api_output[0].delivery_point_barcode)
}
var address_data = objectArray.join([separator = ','])
console.log(address_data)
}
});
}
address("1000 Greenhill Blvd NW, Fort Payne, 35967, AL, USA");
const data = 'Column 19\n1\t2\t3\n4\t5\t6';
require('fs').writeFileSync('./Alabama_Pre_Final.tsv', data);
// i++;
// X(i);
}
}
}
I've looked at your answer above I think it should be easy enough to modify so that it works as you expect, I've done this below. The other functions should be left unchanged. So the function X processes each row then returns a record variable which we append to the records array. After processing is complete we write the records array to the csv file.
async function loadData(filePath) {
if (fs.existsSync(filePath)) {
var tsvData = fs.readFileSync(filePath, 'utf-8');
var rowCount = 0;
var scenarios = [];
parse_tsv(tsvData, (row) => {
rowCount++;
if (rowCount > 1) {
scenarios.push(row);
}
});
return scenarios;
} else {
console.log("loadData: Returning empty..")
return [];
}
}
// Process a row of TSV data
function X(row) {
return new Promise((resolve, reject) => {
if (row && row[7]) {
console.log(row[7]);
request({
url: 'https://us-extract.api.smartystreets.com/?auth-id=e62698e8-c3fc-b929-0f5b-d3b54d0bcd0c&auth-token=cibfMexBdl3HrmwbWY6p',
method: 'POST',
headers: { 'content-type': 'application/json' },
body: row[7],
},
(error, response, body) => {
if (!error && response.statusCode == 200) {
var res = JSON.parse(body);
let objectArray = [];
if (res.addresses[0].verified) {
objectArray.push(res.addresses[0].api_output[0].delivery_line_1, res.addresses[0].api_output[0].components.city_name,
res.addresses[0].api_output[0].components.zipcode, res.addresses[0].api_output[0].components.state_abbreviation)
}
var address_data = objectArray.join([separator = ','])
resolve({ name: address_data.replace(/['"]+/g, '') });
} else if (error) {

How can I remove extra slashes in my response using node?

How can I remove the extra slashes in my responses ?
I have tried JSON.parse and JSON.stringify but they are not working in my code. JSON.parse throws an error like json at position 10.
I pushed the objects of responses in one array. Then I displayed the array of objects (with array) in response.

}
});
};
Try parsing the following element
commitout.push(info1);
change to,
commitout.push(JSON.parse(info1));
Update
Try the following regex
info1 = info1.replace(/\\/g, "");
commitout.push(info1);

Since my original functions do not have any callback, and since async needs callback, i have tried to code a callback in function4 & function5 - but I guess i have not coded it correctly.
I am getting an error in the line where callback is present that states "TypeError: undefined is not a function".
How do i correct this?
Related Question No. 2 : the current code has a timer function whereby function4, function5 and function6 runs with a preset timer. If async works, how do i define a timer whereby the combined set of function4,5 & 6 works based on a preset timer?
Sorry about the long code -- i am new to nodejs and was handed over this code as such and am trying to get this change made.
Thanks for your guidance.
You can instead make function4 and function5 to return promise and then execute function6 only after both function4's and function5's promise gets resolved.
