Problem with selecting from functions

[Rehart-Kcalb]

Version

1.26.0

What happened?

I have query

select title,image,organization_name,organization_logo from filter($1,$2::bigint[],$3,$4);

when I generate code sqlc output such message

column "title" does not exist

When I have tried to return without title, it just return

column column_name does not exist

It didn't show any error only when I write this

select * from filter($1,$2::bigint[],$3,$4);

But after it generate code which return {}interface slice, and I have problem with serializing it. So I rewrite this method by myself everytime when I change my query file.

Relevant log output

# package
sql/query.sql:111:8: column "title" does not exist
