hello! Am I able to attach cloud hook to all flows in project? or group flows to one cloud hook somehow

@Daniil Ponizov yes, I think you can do that using Automations in the in the UI Automations page. In the example below, I’m selecting all flows from the project called “community” and choosing to send me an email any time any FlowRun in this project fails

@Anna Geller Is that a some new feature? I've installed prefect recently and dont see this option in UI

Are you using Prefect Cloud or Prefect Server? Automations is a Cloud-only feature.

because last time, when i need to restart prefect server all flows have been detached

hmm what do you mean by binding flows to the server? when you register your flow, this triggers a GraphQL API call which stores the flow’s metadata in the backend. If you want to later migrate to a new Server instance, you have to make sure to persist and migrate your data as well.

Where is this metadata store and how to migrate it to new server?

it’s stored in your Postgres database. If you use the default configuration (prefect server start), then it gets deployed as a docker container. Usually, you would have to perform migration of your database and upgrade:

prefect-server database upgrade

I think this guide written by Laura Lorenz can be helpful: https://coda.io/@lauralorenz-at-prefect/devops-guide-to-a-perfect-prefect-server Especially this part: https://coda.io/@lauralorenz-at-prefect/devops-guide-to-a-perfect-prefect-server/how-do-i-upgrade-prefect-server-13

thanks a lot!

maybe you can create a tenant?

prefect server create-tenant --name default --slug default

@Anna Geller now I get this error

prefect.exceptions.ClientError: [{'message': 'Uniqueness violation.', 'locations': [{'line': 2, 'column': 5}], 'path': ['create_tenant'], 'extensions': {'code': 'INTERNAL_SERVER_ERROR', 'exception': {'message': 'Uniqueness violation.'}}}]

can it be that you have multiple agents doing the same work?

No, now I have only one agent

you could have a look at this thread, the error message looks similar https://prefect-community.slack.com/archives/CL09KU1K7/p1634730215153300

@Anna Geller error from this thread is about multiple agents run, but I have only one active agent

are you still at the uniqueness violation error? Perhaps you can choose a different tenant name or slug?

Different name fix the problem, but still get the same problem when trying to add cloud hook

@Daniil Ponizov I reached out to the team and this error indicates that you did not provide the tenant id when creating the Cloud Hook, and this is a required input argument to the

create_cloud_hook

mutation. Are you creating this hook from the UI or via API?

@Anna Geller I'm creating it from the UI

Hi @Daniil Ponizov - I'm from the UI team so let me see if I can help here. As a summary, you are trying to create a cloud_hook from the UI in server but you're getting an error saying

Variable "$input" got invalid value null at "input.tenant_id"; Expected non-nullable type UUID! not to be null

- is that correct?

@Jenny I was trying to create web cloud hook with Failed state

Ok. And did you create that with the UI from server? Are you flows showing correctly in the server UI? And all your flow runs?

All flows works correctly and now the problem fixed by itself
