Hi. We are using prefect 0.15.13 server version. The graphql (v2.1.1) throws the below error. It persists even after multiple restarts.

please move code blocks to the thread

you may need this environment variable:

export HASURA_GRAPHQL_V1_BOOLEAN_NULL_COLLAPSE=true

What version were you on before? You might need the

--expose

flag? Are you using the

prefect server start

?
