I am trying to read data from json file but I have some trouble. How can I get items from a json file to individual items?

My json file:

[
 {
  "UserName": "[email protected]",
  "Password": "tests123"
 }
]

My method:

element(by.name('username')).sendKeys(browser.params.UserName);
element(by.name('password')).sendKeys(browser.params.Password);

as a result i get

Failed: each key must be a number of string; got undefined

You are passing an array of object and not an object, thus, you have to be precise in your variable.

Either directly pass an object

{
  "UserName": "[email protected]",
  "Password": "tests123"
}

Or specify the index in the array

element(by.name('username')).sendKeys(browser.params[0].UserName);
element(by.name('password')).sendKeys(browser.params[0].Password);

My Test was also failing with json file then i converted my datafile into ts file like below

export const DataForSearch =
{
    Login:
    { 
        CorrectCreds: { username: '[email protected]', password: 'tests123' }
    }

};

then use this in my test case like

    import {DataForSearch } from "../DataLogin"

const using = require("jasmine-data-provider");

describe("Login Page", () => {
    using(DataForSearch.Login, (data: any, alldesc: any) => {
    it("Login", () => {
    element(by.name('username')).sendKeys(data.username);
    element(by.name('password')).sendKeys(data.password);
    })
    })
})

you can try typescript file, if you still facing issue.If you face any issue let me know
