Question

hey everyone thanks for having this community i recently upgraded from prefect 2021 11 30 to 2022 01 25 and when i run `prefect get flow runs s` i get ```prefect exceptions ClientError message unexpected null value for type String locations line 2 column 5 path flow run extensions path $ selectionSet flow run args where and 0 flow and 0 project name eq code validation failed exception message unexpected null value for type String ``` any tips on how to get around this i do believe that `prefect server database upgrade` was run post upgrade

Yeah I think your gut is right that is looks like the database didn t upgrade I would try to upgrade from the GraphQL pod or container

I think that error is from the change in null behavior from Hasura v1 gt 2

Zanie · Answer

We retain the old behavior in v2 by setting an environment variable It seems like perhaps your image upgraded but the environment did not <https github com PrefectHQ server pull 328 files diff dba09b37045dcad023247e6d17483c5e77aff6c8bea4f51d225279fe79b1e6c3R27> I could be misinterpreting the error though
