Google cloud functions deployment through Cloud Source repositories stopped working - google-cloud-platform

Question

I managed to have a script deploying a GCP Function using the following command :
gcloud beta functions deploy pipeline-helper --set-env-vars PROPFILE_BUCKET=${my_bucket},PROPFILE_PATH=${some_property} --source https://source.developers.google.com/projects/{PROJECT}/repos/{REPO}/fixed-aliases/1.0.1/paths/ --entry-point onFlagFileCreation --runtime nodejs6 --trigger-resource ${my_bucket} --trigger-event google.storage.object.finalize --region europe-west1 --memory 1G --timeout 300s
That worked for a few days, the last one being December 4th. Then, when launched on December 27th ... the command failed with the following output (with debug option added) :
Deploying function (may take a while - up to 2 minutes)...
..failed.
DEBUG: (gcloud.beta.functions.deploy) OperationError: code=13, message=Failed to retrieve function source code

My problem relates to the use of the --source option of this command when it points to a Google Source repository url (it works with gcs bucket or local directory)
I tried using the minimal valid source repository url https://source.developers.google.com/projects/PROJECT/repos/REPO as mentioned in the official doc here ... with no success (same error)
After that, i cloned the official sample « Google cloud functions - hello world sample to GC Repositories and tried to deploy it using an equivalent command ... with no more success (same error). However, i was able to deploy it via a zip uploaded to a gcs bucket in my project or from a local repository but not from Google Source repositories ...
The account used to deploy the Function (xxx-compute#developer.gserviceaccount.com) has the following right :
Stackdriver Debugger Agent
Cloud Functions Developer
Cloud Functions Service Agent
Editor
Service Account User
Source Repository Writer
Cloud Source Repositories Service Agent
Storage Object Creator
Storage Object Viewer
Any help would be greatly appreciated

As mentioned in my last comment to #Raj, the problem was due to a bug in GCP ... that is now fixed. Support « people » where kind and reactive.
All is working as expected now !
