Google Cloud Storage Connector fails with error: *"...does not have storage.buckets.list access to the Google Cloud project"*

KNIME Analytics Platform

Hi,

I need to download files from a client’s Google Cloud Storage using a provided service account. The flow should actually be quite simple and look something like below (the loop may not be necessary)

gcp_fetch

For some reason, the Google Cloud Storage Connector always fails with error:

“…does not have storage.buckets.list access to the Google Cloud project”

I know that the service account is good and that the Authentication node works because I used it before to connect to a database to run a query. And, I can connect and list the files because I can do it in a Jupyter Notebook. I don’t write code, but I managed to list and fetch files (1 at a time) with copy 'n paste code from the Google documentation but I want to do it Knime which is my primary workspace.

I thought it may be something I missed in the Google Authentication Node but I am sure that I have all the necessary Scopes included

GCPNode1

Is there something I am missing?

Could the Scopes need something like this:

https://storage.googleapis.com/storage/

And you might want to check the configuration of your cloud storage connector according to this description:

Hi @mlauber71

I looked at the scopes on the Google Authentication node but the only scopes available are

and I tried them all.

I am beginning to think that it must be something in the way my client assigned rights to the service account. I am sure that I am not the only person to use the nodes, so it must be working for other users.

tC/.
