Error: Invalid HTTP method/URL pair when using getDownloadURL on a file produced by the Transcoder API

I am using the Transcoder API to format videos into a 1:1 aspect ratio. The source video file is stored in a Firebase Storage bucket. When the transcoded file is generated, it does not have an access token, so to view the file, I can manually create the access token using the console. This way I am able to get a URL that I use to access the transcoded file.

I want generate a download URL in my cloud function for the the ChromeCast.mp4 file in picture below: enter image description here

When I run the following code, I get "Error: Invalid HTTP method/URL pair." in my log with the following code:

            // Create a download URL for transcoded file

            const { getStorage, getDownloadURL } = require('firebase-admin/storage');

            var newBucket = `*MY-BUCKET-NAME*.appspot.com/transcoder/`
            var newName = `ChromeCast.mp4`;

            console.log(`newBucket: ${newBucket}`);
            console.log(`newName: ${newName}`);

            const fileRef = getStorage().bucket(`${newBucket}`).file(`${newName}`);
            const downloadURL= await getDownloadURL(fileRef);

            console.log(downloadURL);

The line "const downloadURL= await getDownloadURL(fileRef)" is generating the error. I have tried the following variations of the bucket name:

var newBucket = `*MY-BUCKET-NAME*.appspot.com/transcoder%2F`

var newBucket = `*MY-BUCKET-NAME*.appspot.com/transcoder`

But I still get the same error.

I have also tried removing the following code variation, but get 'Error: Not Found'

        var newBucket = `*MY-BUCKET-NAME*.appspot.com`
        var newName = `/transcoder/ChromeCast.mp4`;

        const fileRef = getStorage().bucket(`${newBucket}`).file(`${newName}`);

        const downloadURL= await getDownloadURL(fileRef);

I am using a hardcoded bucket for testing purposes. I want to generate a download URL so I can update a document with the new URL, replacing the URL to original video file

The string "transcoder" is not part of your bucket name. It's part of the path to the object you're trying to work with. Your variables should look like this:

var newBucket = `*MY-BUCKET-NAME*.appspot.com`
var newName = `transcoder/ChromeCast.mp4`;
