Hi everyone. Is anyone familiar with the manner in which a manual_only task can be triggered from the UI? The logger results in

finished task run for task with final state: 'Paused'

, and I'm not sure as to how this would be fixed.

Hi @Ethan Shenker! Manual-only tasks can be resumed/approved from the flow run page to which the task run belongs or from the task run page itself in the actions bar:

Hey @nicholas, I really appreciate the response. Unfortunately, I'm still slightly confused. My UI doesn't have either the global notifications bar, nor the column in the "task runs" table that allows for unpausing -

Hm, I believe the pause/resume functionality should still be able available in Prefect Server - which version are you running? To push to Cloud, you'll need to create a Cloud account (you can do so by visiting cloud.prefect.io), grab a User token from the User > Api Tokens page in the left sidebar, and then running:

$ prefect backend cloud && prefect auth login -t <<YOUR_TOKEN>>

I'll try registering with the cloud, but is there a command I can run to determine the version of the Prefect server I'm running?

Yup ~! You can run

prefect version

I'm currently running 0.12.3

Ahh that explains it! 0.13.0 released a completely new version of the UI, including notifications and the approval functionality.

Got it. Unfortunately, I'm using a regulated service that can only run on python3.6, which I believe would prevent me from updating my version of Prefect.

Got it - that's fine! In which case it sounds like Cloud is a better solution for you since you'll always have the updated UI and API functionality.

Hi Ethan - you should still be able to update your version of Prefect; nothing has changed with the versions of Python we require / support

Hi @Chris White, I updated my version of prefect to 0.13.2, but now when I try

prefect server start

,

prefect agent start

, and running my file, I get an error that's never been thrown before: requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: http://localhost:4200/graphql

You'll want to run

prefect backend server

before you interact with your local server and

prefect backend cloud

for interacting with Cloud 🙂

I have a shell script that runs the file, and each time that script is ran, the

prefect backend server

command is also ran. However, that HTTP error still persists.

Hi Ethan, there were a few changes in 0.13.2 that might cause this. In particular you’ll need to first create a project and then provide the project name when you register your flow

Hey Chris, I created a project called Pricing Flow within the Prefect UI, and then when I registered my flow from the source code I used the

overwrite_flow.register(project_name="Pricing Flow")

command, but the same HTTP 400 error is being thrown

can you post the full traceback of the error? And can you confirm that both you are using prefect 0.13.2 for both the Server start and the flow registration?

When you ran

prefect server start

did you have 0.13.2 installed?

I'm running

prefect version

right now, and it displays 0.13.2, and I'm going to run the server again and try from there

it takes some time for all the services to become healthy but if you see the Prefect Server ASCII art then you should be good. Next I’d visit the UI at localhost:8080 and confirm everything looks good there as well

The localhost UI works fine, and I rerun

prefect backend server

,

prefect agent start

, and I try to rerun my flow but I get the same client error

OK can you try setting

PREFECT__CLOUD__DIAGNOSTICS=true

as an environment variable before you register your Flow? This will show the GraphQL call your client is making (it’ll be long)

I put that line in my .bashrc file and I also ran

export PREFECT__CLOUD__DIAGNOSTICS=true

but nothing changed

Sure @Ethan Shenker , you can always run

pip install --force-reinstall prefect==0.12.3

@nicholas thank you so much, I'll let you know in a moment as to whether or not that works

Glad to help @Ethan Shenker - when you're on less tight of a deadline the upgrade is well worth the trouble 😄 good luck!

yup glad you’re unblocked!

I definitely agree @nicholas - I'll likely look into it over the weekend because the ability to unpause would make part of my workflow much more simple. However, I still don't know what the root cause of the issue that had presented itself was, so I'll likely be back on here again soon! Thank you both very very much 🙂
