file-video | frontend interface relies on an open source API gateway | Continuous Deployment library

The problem is the toggling of the class is dependent on only the last input in the collection the way you have written it in the loop like that.

You could use filter() to get collection of the ones that are empty (if any) and use that collection length to determine the class toggling.

Using toggleClass() with it's boolean second argument is also simpler than writing both addClass() and removeClass() in a conditional

Something like:

• You want to retrieve all files under the all sub folders in the specific folder.
• From retrieved all files, you want to retrieve only video files. And you want to retrieve the number of files, filenames and the total length of the video files.
• You want to achieve this using Google Apps Script.

If my understanding is correct, how about this answer? Please think of this as just one of several possible answers.

• I think that your error of Cannot read property 'length' of undefined is due to the following 2 reasons.
  1. About getVideoDuration(folderId, files) in traverseFolder, you send folderId, files as the arguments. But at the function of getVideoDuration, the script is getVideoDuration(folder,folderId, files). By this, the folder ID is not used. And also, files is not used in getVideoDuration.
  2. From this official document, the query parameter of access_token cannot be used now. So it is required to use the access token at the request header. I thought that I had modified my answers related to this. But I had forgot to modify to this answer. I apologize for this.
• sum is not declared. By this, an error occurs.
• When the files except for video are in the folder, an error occurs at obj.files[i].videoMediaMetadata.durationMillis.

When above points are reflected to your script, it becomes as follows.

Your error description is not very precise, but I assume that the problem is that you are not adding the class (string), but its index.

I tried all the way to replicate this issue. But not able to find any issue with this code.

• I am using Primeng Version 7.

I fixed typo in your json "lakeybel": "Scarface" it should be "key": "Scarface". Even With typo it is working fine.

Just try again with correct JSON and use as given in documentation .

Also check if you see any console error or warning.
