I'm trying to set up a sink that will export a certain set of Google Cloud Platform logs to a Google Cloud Storage bucket but can't get it to work and the documentation doesn't seem to match what's happening on the GCP console.
Steps (all using the GCP console):
1) I set a filter on the log viewer which is showing me the expected logs
2) I choose "Create Export" and fill in the fields:
After hitting OK, I get a message: Unknown user email address: defaultServiceToGCSSink@logging-somedigits.iam.gserviceaccount.com
Apparently the sink is trying to use the name I gave it as the user that will be writing to the storage bucket.
When I check the bucket I can see that a user with that email was added as an owner to mylogsBucket. but still no logs in the bucket.
I also added the group [email protected] as an owner to the bucket (as the documentation states) but nothing works and no logs are exported to the bucket (and I've waited for more than a couple of hours).
Should I be adding that new user to IAM? I tried to but it wouldn't accept the email address as a valid user name.
Remove the gserviceaccount.com user from the bucket ALCs and then try creating the sink.
Is there any chance you successfully created the sink at some point in the past and later deleted it? My guess is the service account was put on the bucket earlier, and now the sink creation is failing because it's trying to add the account again.
