conditional useQuery without input

How to use the enabled option for useQuery that doesn't has an input?

 const { isError, error } = trpc.iam.logout.useQuery(undefined, {
    enabled: isEnabled,
  });

 const { isError, error } = trpc.iam.logout.useQuery(undefined, {
    enabled: isEnabled,
  });

I'm passing undefined and TS is not complaining, only on runtime I get

app-index.js:33 Query data cannot be undefined. Please make sure to return a value other than undefined from your query function. Affected query key: [["iam","logout"],{"type":"query"}]

How to properly use this feature?

a query is enabled by default, so you don't need enabled: true

I'm a bit late but perhaps you're looking for mutations , not queries. Makes no sense to have a logout as a query. Queries are data loaders (get data) Mutations are actions (do something)

I was going to use a mutation, but the mutation is expecting that I pass arguments

Not if you pass undefined just like you did here no?
