Does anybody know of a way to get the input parameters of a task run to show up in the UI? Kind of like how

@task(result=PrefectResult())

makes the output of the task run appear in the UI, except I'm looking to do this with the inputs as well.

@Marvin, I am running prefect server and worker in the same kubernetes cluster, both version 3.7.5. I am currently seeing the following error log in my prefect server:

WebSocket connection rejected: 'prefect' subprotocol required when auth is configured.

The worker also has error logs, because of the server rejecting its connection.

What’s the best way to prune\cleanup old data on Prefect Server? the

.prefect

directory reached a size of 428G.

I have noticed that flow runs seem to get stuck in a running state. This seems to be happening more and more frequently. We are using Prefect 2.4.0 and using K8s and GCS for infrastructure. I have found that for these flow runs I am seeing logs on the agent like this

prefect.agent - An error occured while monitoring flow run <flow_run_id> The flow run will not be marked as failed, but an issue may have occurred.

Hey Guys I want to setup a flow dependency for my task, basically I am running a flow, inside which I have a flow which downloads some data and then after this data has been downloaded I want to run some tasks, but when I try to do so the download flow runs successfully but the tasks after that end up failing, any idea why could that be happening and how can I fix it?

@Marvin why does my deployment show as not ready with the error "This deployment has not been polled in the past 60 seconds"

Hi all, my company is testing prefect and I am having trouble installing a kubernetes agent, which I suspect is because of the company proxy. When I try to install the agent the logs say that it is being registered, but then eventually I get an SSL error.

requests.exceptions.SSLError: HTTPSConnectionPool(host='<http://api.prefect.io|api.prefect.io>', port=443): Max retries exceeded with url: / (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1091)')))

Is there a way to provide proxy credentials when starting the agent? I've tried using the --env flag to supply proxy information. Or is there something similar to a --verify=false that I can set?

@Marvin does prefect3 requires a running prefect server ?

Hi Prefect, I was wondering if it is possible to connect the prefect UI to an internal network, that might not be available from the host I'm viewing the UI with? It seems that currently

server.ui.apollo_url

is called from the browser (and not from the server where the UI is running). For example, I have a docker-compose managed prefect server somewhere with an internal network called

prefect-server

, which has both

apollo

,

ui

, and the other prefect server services. Using

apollo_url="<http://localhost:4200/graphql>"

only works if I also bind

apollo:4200

to the local

4200

port where I'm running the browser from. For example setting

apollo_url="<http://apollo:4200/graphql>"

and letting the UI -> GraphQL connection go via the docker network wouldn't work afaik. In this case I see the following error in my browser's JS console:

VM9:1 POST <http://apollo:4200/graphql> net::ERR_NAME_NOT_RESOLVED

Hi, I am trying to register a simple flow in a server that I run in a docker locally. I first built a docker image on top of

prefecthq/prefect:latest

image, which also copied my python script

/src/test.py

and ran

prefect backend server

. Then in the

docker-compose.yaml

generated by

prefect server config

, I added a service

client

whose command is

python /src/test/py

. After running

docker-compose up

, I got the following error from the

client

service:

requests.exceptions.ConnectionError: HTTPConnectionPool(host='localhost', port=4200): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f24823ea0d0>: Failed to establish a new connection: [Errno 111] Connection refused'))

Meanwhile, I can access UI and on UI it’s connected to Apollo endpoint successfully. It seems like

client

fails to connect to server at localhost:4200?
