103 Lab Instructions: • Use a previously made flow • Create a Cloud profile (or use an existing one) • Authenticate for the CLI • Make an email notification automation for flow run completion • Run the flow a few times from the CLI • See the event feed in the UI • Stretch: create a Slack notification automation

Getting this error when trying to auth with the api key? Any ideas?

Unable to authenticate with Prefect Cloud. Your key is not in our expected format.

We’ll get back together in 3 minutes at 9:50pm ET.

Automation action is failing for me with this

"reason": "The notification block was invalid: ValidationError(model='PrefectCloudEmail', errors=[{'loc': ('emails',), 'msg': 'value is not a valid list', 'type': 'type_error.list'}])"

Recording from day 1: https://us06web.zoom.us/rec/share/XZ3md8QzM1kFDMdCCrPVR5l7FO-lLq_Neg4k3mV9s2QjA9o0AmDDE3wTBAVAdpbc.jXdRf7bGeRHTVRSh Passcode: Wb4Xf^4t

See you at at 7pm ET (a little under an hour and a half from now).

Kicking off momentarily in the same Zoom room as yesterday. 🙂

104 Lab Instructions 📚 : • Use a flow from the 103 lab • Make a deployment via interactive CLI commands • Start a worker • Run a deployment from the UI • See the flow run logs in the UI • Stretch: Create a deployment that has default parameters & override the default parameters at runtime in the UI

Can we get the slides for today?

Day 2 slides:

Side note, if you get stuck, you can take a look at the Tutorial in the docs. 🙂 (just swap out the script for one that you used in 103)

I got a flow deployed (thumbs)!

GH Issue for multiple prefect.yaml files.

@Elizabeth Bing - 🧵 for error

105 Lab ✍️ : • Create a deployment that uses one of the new workflow patterns you’ve seen in this module. • See the prefect.yaml. Use GitHub or other git-repo-based code storage. ◦ Don’t forget to push your code! • Add a schedule. • Pause the schedule.

Flow timeouts - use

timeout_seconds

param in the flow decorator: https://docs.prefect.io/2.11.5/api-ref/prefect/flows/

We’ll get back together in 2 min at 8:55pm ET.
