Hi everyone, I'm using the Prefect Helm Chart to deploy a Prefect Server in my self-hosted Kubernetes Cluster. The setup works fine, the tenant and agent are being set by Helm. I have also created a L7 Ingress pointing to Apollo. The UI is working, but when I try to register a simple Flow, I receive this error:

requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: http://{endpoint}:80/graphql/alpha

where endpoint is the L7 ingress endpoint. Is there a way to debug what's going wrong?

Hi @Hygor Knust, I will forward this to the team

Thanks! To add more information, I can access the GraphQL web client using this endpoint and there are no errors in the logs

Oh so the error is only when using the UI?

No, everything seems to be working, the error occurs when I run this python script

import random
from prefect import task, Flow


@task
def random_number():
    return random.randint(0, 100)


@task
def plus_one(x):
    return x + 1


with Flow('My Functional Flow') as flow:
    r = random_number()
    y = plus_one(x=r)


flow.register(project_name="Sample Project")

Hey @Hygor Knust -- what did you set the

ui.apolloApiUrl

to when you installed the Helm chart?

Hi @Zanie, I created an Ingress forwarding

http://{endpoint}

to

http://{apollo-ip}:4200

so I don't have to change any configuration if the Apollo IP changes. I thought that this ingress could be the problem, but I set it as the URL in the UI and it connected successfully. and I am also able to connect to it using my browser.

What does

prefect diagnostics

output?

I get the same error if I try passing the Apollo SVC ip

Can you try running

prefect backend server

?

Oh, I found it. There was a mismatch between the Prefect Server and my local prefect package

Wonderful 🙂

Thanks for your support!
