Mongoose Object.save() only working if called twice

I know this sounds rediculess... In my function index() I retrieve a Model for a specific collectionName promted by commandline parameters. After a async AXIOS API call a saveToDB(response, model) is called.

export async function index(collectionName) {
  let model = getModelForCollection(collectionName)

  await axios.get(url)
            .then(resp => {
                saveToDB(resp.data, model)
                    .then(saved => {
                        ...
                    })
            })
}

async function saveToDB(response, model) {
    
  const word = new model({response})
  await word.save()
     .then(() => {
         console.log("saved")
     })
}

So basicly this should easily work, but the strange thing is. This does only! work, if I save another document prior to calling saveToDB() in index(). Changing the function to;

export async function index(collectionName) {
  let model = getModelForCollection(collectionName)

  let word = new model({word: 'WORT'})
  await word.save().then(() => {
      console.log("saved")
  })

  await axios.get(url)
            .then(resp => {
                saveToDB(resp.data, model)
                    .then(saved => {
                        ...
                    })
            })
}

Is there anything strange going on I am not aware of? Excuse my super unspecific question.

Why are you consuming and "awaiting" the Promises at the same time. Why don't you keep it simple like this:

export async function index(collectionName) {
  try {
    let model = getModelForCollection(collectionName)

    let resp = await axios.get(url);
    let saved = await saveToDB(resp.data, model);
  } catch (error) {
    console.log("Error");
    console.log(error);
  }
}

async function saveToDB(response, model) {
  try {
    const word = new model({ response });

    let writeStatus = await word.save();
    console.log("saved");
  } catch (error) {
    console.log("Error");
    console.log(error);
  }   
}

Maybe you should read the docu: https://mongoosejs.com/ or search for related questions. I guess its not a mongoos problem.
