Henry @Henry: Hello. We upgrade from 0.15.14 to 1.1.0 and it seems like our flows are still running but nothign shows up on the dashboard unless we pick a project

Kevin_Kho @Kevin_Kho: You mean the main dashboard just to confirm?

Henry @Henry: yes the main dashboard with the overview/flows/calendar tab

Kevin_Kho @Kevin_Kho: you’re on Cloud or Server?

Henry @Henry: server
migrations seemed to run fine

Kevin_Kho @Kevin_Kho: when you go to the dashboard and open the console do you get an error?

Henry @Henry: it looks like we’re geting the followign error

{
  "type": "http-log",
  "timestamp": "2022-03-25T18:16:10.065+0000",
  "level": "error",

        "x-hasura-role": "admin"
      },
      "error": {
        "path": "$.selectionSet.flow_run.args.where.flow_id._eq",
        "error": "unexpected null value for type \"uuid\"",
        "code": "validation-failed"
      },

    },

      "ip": "10.20.1.118",
      "method": "POST",
      "content_encoding": null
    }
  }
}

Kevin_Kho @Kevin_Kho: that does seem like migrations didn’t work. could you try running them manually?

Henry @Henry: any clue on which migrations i should be running?
seems like the console works
i did not see any flow_run.flow_id null’s

Solution

Michael_Adkins @Michael_Adkins: This looks like your Hasura/Prefect Server versions are not matched.
This environment variable is needed for Hasura 2+

export HASURA_GRAPHQL_V1_BOOLEAN_NULL_COLLAPSE=true
