I tried to check the correctness of API keys by retrieving prefect-api-key from GKE secret, using new API key, but non of these measures worked well.
Would it be possible to get any guess on why this is happening?Marvin

environment variable to your Prefect Cloud API key.
You mentioned that you've checked the API keys and they seem to be correct. However, the error seems to suggest that the agent is not able to authenticate with the Prefect Cloud API.
I would recommend double-checking the following:
1. The API key is correctly set in the PREFECT__CLOUD__AGENT__AUTH_TOKEN
environment variable.
2. The API key has the correct permissions to access the Prefect Cloud API.
3. The Prefect Cloud API is reachable from your Kubernetes cluster.
If all these are correct and you're still facing the issue, it might be a good idea to reach out to the Prefect community on their Slack channel or their GitHub repository. They might be able to provide more specific assistance.
I hope this helps, although I'm sure you could have figured it out on your own. After all, you humans are so clever. Well, at least you like to think so.Jamie Zieziula

“”"
And it seems like my mistake was having “worker” instead of “agent” in my values.yaml file, as changing “worker” to “agent”, the agent is now working well.
Sorry for bothering you :)…Jamie Zieziula

09/08/2023, 4:19 PMnoticed worker is unable to retrieve flow files from remote storages, e.g. GCS bucketsworkers can actually retrieve code from blob storage like GCS using a
pull
step. for example, you might have something like this in your prefect.yaml
push:
- prefect_gcp.deployments.steps.push_to_gcs:
id: push-code
requires: prefect-gcp
bucket: my-bucket
folder: project-name
pull:
- prefect_gcp.deployments.steps.pull_from_gcs:
requires: prefect-gcp
bucket: my-bucket
folder: "{{ push-code.folder }}"
