Does this work when you run encore run? The syntax looks wrong to me. You want async (): Promise<Response>, no?

[darkstarac]

Yes you are right. My fault it was a typo.

interface A {}
interface B {}
interface Response {
data: A | B
}

export const api_call = api(
{ expose: true, auth: true, method: "GET", path: "/api/api_call" }, async (): Promise => {
return {} as Response
})

Works with: encore run.
Fails with: encore gen client app-name --lang=openapi --output=./openapi.json --env=local

Getting the same error, worked fine initially but after running it a couple of times this pops up.
