Error Encountered: In a For Loop, there is a TypeError where the property '0' cannot be read as

I am currently facing an issue while attempting to iterate through data retrieved from an API request. The structure of the data is as follows:

[ { kind: 'qpxexpress#tripOption',
    saleTotal: 'USD107.70',
    id: 'fANabOjuLoDMb9zppwbeXL002',
    slice: [ [Object] ],
    pricing: [ [Object] ] },
  { kind: 'qpxexpress#tripOption',
    saleTotal: 'USD107.70',
    id: 'fANabOjuLoDMb9zppwbeXL003',
    slice: [ [Object] ],
    pricing: [ [Object] ] },
  { kind: 'qpxexpress#tripOption',
    saleTotal: 'USD107.70',
    id: 'fANabOjuLoDMb9zppwbeXL001',
    slice: [ [Object] ],
    pricing: [ [Object] ] } ]

My for loop implementation seems to be causing a type error during execution. I'm finding it challenging to troubleshoot this issue. Can you help identify what might be missing in my code?

  request(options)
  .then(function (response) {
    //.log(response.trips.tripOption)
    let selects = 0
    for(let i = 0; i < response.trips.tripOption.length; i++) {
      if (response.trips.tripOption[i].selected) {
        selects++
      }
    }
    return selects;
    console.log('hello' + ' ' + selects);

  })
  .catch(function (err) {
    console.log(err);
  });

Answer №1

There appears to be a mistake in Line 6 of your code, where you have written tripOptions instead of tripOption.

Additionally, remember to include console.log() before the return selects statement.
