Hi all, I am having a problem with creating an agent using prefect server as a backend. When I try to kubectl apply the agent manifest I get the following error:

Copy code

prefect.exceptions.ClientError: Malformed response received from API.

My config.toml looks as follows:

Copy code

[server]
host = "<http://10.2.36.47>"
endpoint = "<http://10.2.36.47:4200/graphql>"
backend = "server"

There are several ways how you can configure that. CLI

Copy code

prefect backend server

This will update the

~/.prefect/backend.toml

file to “server” as well. Using an environment variable

Copy code

export PREFECT__BACKEND="server"

In a Kubernetes YAML manifest When deploying to Kubernetes, you can do: You need to add the following environment variables:

Copy code

env:
        - name: PREFECT__BACKEND
          value: server
        - name: PREFECT__CLOUD__AGENT__AUTH_TOKEN
          value: ''
        - name: PREFECT__CLOUD__API
          value: "<http://some_ip:4200/graphql>" # paste your GraphQL Server endpoint here

Thanks for your response! I updated the yaml and now I get HTTP Connection read timed out. Is there a way to increase the timeout duration using environment variables?

Yup! https://discourse.prefect.io/t/is-it-possible-to-increase-the-graphql-api-request-timeout/219

In this case I was able to get it running and the issue was that I did not have a tenant in Prefect Server. However now when I try to register a flow I get a HTTPConnectionPool Error. I tried increasing the timeout, but no luck. I believe it is an issue with our company proxy. Is there a way to provide prefect with proxy authentication information?

I figured it out! Adding the server to the NO_PROXY environment variable fixed this issue
