I have a self-hosted prefect server running 0.15.13 that I am trying to set up a Slack integration for via webhook. I am clicking on the "secret link" in the docs to get the webhook URL. But when I paste this into the Prefect UI and click Save, I get the error:

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

I searched the community and saw some recent discussion about

tenant_id

in this forum related to the 1.0 release, but none in this exact context I think. Do I need to install a newer version of Prefect, or click an older version of the secret link, to make this work?

Not sure why that is the specific error message but Server doesn’t have secrets. It’s the Cloud only feature.

Thanks for the response! I'm aware that Secrets are a cloud-only feature, but what I'm trying to do (Slack integration) does not involve Secrets (as far as I know). I only called it a "secret" URL because that is what the docs call it:

Ah ok I see what you are saying. So this looks like server migrations didn’t run or it might be this GraphQL Validation failure. What is your Hasura version?

Thanks. I am running

v2.1.1

of Hasura. Does that mean I should try setting the

HASURA_GRAPHQL_V1_BOOLEAN_NULL_COLLAPSE

environment variable?

Yes

Actually, it appears this variable is already set inside of

prefect/cli/docker-compose.yml

.

Oh that’s weird. Do you have a tenant when you spin up the UI? I think this might be an issue with webhooks

I'm not sure how to check whether I have a tenant. Would that be visible in the UI itself, or in a log somewhere?

Visible in the tenant

I have a team called "default", is that the same thing as a tenant?

Yes that should be. Can you try using the Interactive API to see if you can query the tenant route? Should be something like:

query {
            tenant {
                id
                name
        }
    }

Assuming you have an id, I think this is an issue with the webhook

Thanks, here is the response:

{
  "data": {
    "tenant": [
      {
        "id": "ba245c42-e7bf-46ff-a879-fee1ef3f0a8d",
        "name": "default"
      }
    ]
  }
}

Ah crap sorry my bad. Let me dig into this now

Hasura version is

v2.1.1

and this is running via docker-compose.

2.1 seems too high for 0.15.13 but i’m not sure
