Cypress test throws an error message when using an array

[thepixelhead]

In a cypress test case I use this line of code and cypress throws an error message that I do not understand. See below. No idea what to do.

Any idea?
Any solution possible?

Code:

const months = [
            'JAN', 'FEB', 'MAR', 'APR', 'MAY', 'JUN', 'JUL', 'AUG', 'SEP', 'OCT', 'NOV', 'DEC'
          ];
      
// Create an object to store the values dynamically
const values = {};
      
// Use a loop to iterate over each month
months.forEach((month, index) => {
            cy.get('.tabele1 > tbody > tr.table_row3 > td:nth-child(1)').each(($e1, rowIndex, $list) => {
              var titletext = $e1.text();
              if (titletext.includes('Some Headline Text')) {
                cy.get(`.table1 > tbody > tr.table_row3 > td:nth-child(${index + 2})`).eq(rowIndex).then(function (amount) {
                  // Dynamically store values in the object
                  values[`valueMA_${month}1`] = amount.text().trim();
                  // values[index] = Number(umsatz.text().trim());
                });
              }
            });
 });

// Example assertions in a loop
months.forEach((month, index) => {
            expect (values[`valueMA_${month}1`]).to.equal(400);
});

Cypress error message:

AssertionError
expected undefined to equal '400'

The error refers to this line of code:
expect (values[`valueMA_${month}1`]).to.equal(400);

What is wrong with the code? I do not see it ...

Thank you very much!

I solved it like this:

const months = [
            'JAN', 'FEB', 'MAR', 'APR', 'MAY', 'JUN', 'JUL', 'AUG', 'SEP', 'OCT', 'NOV', 'DEC'
          ];

const values = [];
    
// Use a loop to iterate over each month
        months.forEach((month, index) => {
            cy.get('.table1 > tbody > tr.table_row1 > td:nth-child(1)').each(($e1, rowIndex, $list) => {
                var titletext=$e1.text()
                if (titletext.includes('Specific Headline Text')) {
                    cy.get('.tabelle1 > tbody > tr.table_row1 > td:nth-child(' + (index +3) + ')').eq(rowIndex).then(function (amount) {
                        values[`valueMA_${month}1`] = amount.text().trim();
                        expect (values[`valueMA_${month}1`].toString()).to.equal('100');
                    });
                }
            });
        });
