await search in NodeJS

This is a very simple question as I'm new to both JS and cloudinary.

I got the following code working:

cloudinary.v2.search
  .expression('resource_type:image AND tags=kitten AND uploaded_at>1d AND bytes>1m')
  .sort_by('public_id','desc')
  .max_results(30)
  .execute()
  .then(result=>console.log(result));

Yet I want to put it into a function and return the search result, which seems impossible for me to do within the `then` function.

This the best I've come up with so far:

const searchImages  = async (folder) => {
  return await cloudinary.v2.search
    .expression('folder:${folder}')
    .execute()
    .then((result) => {resolve(result)})
}

 

Yet, it is not working. I got

 

The promise rejected with the reason "#<Object>".] {
  code: 'ERR_UNHANDLED_REJECTION'
}

 

This might be a very simple / sill syntax issue, but I just cannot fix it myself.

Please help.

  Hi,

  Adding a catch() to handle the error will help you to see what exceptions your code is encountering. And with that, the thrown exception is because it is required to use a backtick (`) when using the variable ${folder} when concatenating it with a string value.

  For example:

  var cloudinary = require('cloudinary').v2;
  
  cloudinary.config({
    cloud_name: 'your_cloud_name',
    api_key: 'your_api_key',
    api_secret: 'your_api_secret',
    secure: true
  });
  
  const searchImages = async (folder) => {
    let promise = new Promise((resolve, reject) => {
      cloudinary.search
        .expression(`folder:${folder}`)
        .execute()
        .then((result) => { resolve(result) })
        .catch((error) => {
          console.error(error)
        });
    });
  
    let result = await promise; // wait until the promise resolves (*)
  
    return result;
  
    //console.log(result); // Admin API search results
  }
  
  searchImages('targetFolder').then((returnedValue) => {
    console.log(returnedValue);
  });
