The Lodash project, unable to get '_invert' method to work correctly

Hi everyone,
I have tried to use the code from the solution and I am still getting an error -after enough time spent on “stare and compare” i now need someone to point out the basic error I have made before my head explodes!

Link to the Lodash project - I am trying to complete the _invert method exercise:
https://www.codecademy.com/paths/full-stack-engineer-career-path/tracks/fscp-javascript-syntax-part-ii/modules/fecp-practice-javascript-syntax-arrays-loops-objects-iterators/projects/lodash

Here is a screen shot of my code and the error:

here is the code so you can copy and paste to test if needed:

invert(object) {
  let invertedObject = {};
  for(let key in object){
    const originalValue = object[key];
    invertedObject = {originalValue : key}
  }
  return invertedObject;
}

here is the error message ( number 4 fails) if the screenshot isnt clear:

$ node test/invert.js
_.invert() Tests:
1 - _.invert() is defined - Passed!
2 - Returns an object with key and value inverted for a single key-value pair - Passed!
3 - Original key is not present after the key-value pairs have been inverted - Passed!
4 - Returns an object with all keys and values inverted - Failed: _.invert({originalKey: “originalValue”})[“originalKey”]) returned undefined instead of anotherKey.

please help!

I made a very small tweak to your code so I could run it outside the lesson:

invert = (object) => {
  let invertedObject = {};
  for(let key in object){
    const originalValue = object[key];
    invertedObject = {originalValue : key}
  }
  return invertedObject;
}

console.log(invert({'a': 'b', 'c': 'd'}))

the expected output:

{'b': 'a', 'd': 'c'}

this is clearly not what we are getting:

{
  originalValue: "c"
}

the problem seems to be here:

invertedObject = {originalValue : key}

you assign an object to invertedObject variable, instead of adding a key value pair to the invertedObject

thank you - the code I have shown is the code from the solution video which passes all tests!!!
i have managed to find a solution:

 invert (object) {
    let invertedObject = {};
    let originalValue;
    for (let key in object) {
      originalValue = object[key];
      invertedObject[originalValue] = key;
    }
    return invertedObject;
  },

Now I need ot try and understand how it works but I hope this is useful to anyone else who finds that the solution provided in the course video does not actually pass the test.

thanks
Jay
