Improved error messaging on generate failure

[cdaringe]

Problem

$ gqty generate yields:

query "SELECT gf
        from
            graphql.field gf
        where
            gf.name = $1
            and gf.parent_type = $2
            and coalesce(gf.parent_arg_field_name, '') = coalesce($3, '')" returned more than one row

and exits with code 1.

Discussion

• I'm not asking for help solving my particular issue, however
• At the boundaries of operations where gqty is working w/ it's deps and asserting on fallible operations, some logging/messaging/etc could be helpful to isolate where/why the problem is occurring

gqty generate only does an introspection query, there isn't anything special, you can do introspection queries outside of gqty and also debug from there

clients that also do introspections https://altair.sirmuel.design/ https://github.com/graphql/graphiql https://github.com/graphql/graphiql
