Unable to resolve "Failed: each key must be a number of string; got undefined" in protractor using Typescript

My data file looks like this. Only first set passes but second iteration, it fails at email address

export const userTestData = {

    scenarios: {

        scenario1: {
            firstName: 'John',
            lastName: 'Doe',
            city: 'Indianapolis',
            password: 'MyApp@123',
            emailAddress: 'Test1@gmail.com',
            addressLine1: '52nd BroadRipple Street',
            zipCode: 43464
        },

        scenario2: {
            firstName: 'Mark',
            lastName: 'Baker',
            city: 'Westfield',
            password: 'Test@123',
            emailAdd: 'Test1@gmail.com',
            addressLine1: '12412 Ballantyne Street',
            zipCode: 23053
        }
    }
};

Any help is greatly appreciated. Not sure why it is throwing error only for 2nd iteration. Ist iteration all the values are accepted and test is passed

Take a look at example how to use Data Provider from object in the npm description to the package

You have to re-write your Data object as:

export const userTestData = {

    scenarios: {

        'scenario1': {
            firstName: 'John',
            lastName: 'Doe',
            city: 'Indianapolis',
            password: 'MyApp@123',
            emailAddress: 'Test1@gmail.com',
            addressLine1: '52nd BroadRipple Street',
            zipCode: 43464
        },

        'scenario2': {
            firstName: 'Mark',
            lastName: 'Baker',
            city: 'Westfield',
            password: 'Test@123',
            emailAdd: 'Test1@gmail.com',
            addressLine1: '12412 Ballantyne Street',
            zipCode: 23053
        }
    }
};
