Nothing is happeneing

I followed your exact instructions but I'm not seeing anything at the destination bucket.

When I use the "TESTING" section in the Cloud Function I get this error"
TypeError: Cannot read property 'bucket' of undefined at exports.logTransformer (/srv/index.js:35:40) at /worker/worker.js:825:24 at at process._tickDomainCallback (internal/process/next_tick.js:229:7)

I used the console to create the Function:

I choose Runtime: Node.js 8

In the Environment section I added:
Environment variables
DEST_BUCKET_NAME -> destestexport

I set the following configs in the Trigger section
Trigger type -> Cloud Storage
Bucket -> bucketname
Event Type -> Finalize/Create

I copied the index.js and package.json and paste them at the Source
And I set
Function to execute -> logTransformer

Can you let me know what I missed. I would appreciate the help.
Thanks

@MONTATICH the function is written only when you place a file in bucket. It doesnt run directly.
