required usecase-response into usecase2mutation #24
Description
Problem
I'm trying to use usecase2mutation with an usecase that don't needs a response, but the usecase2mutation requires it
my usecase:
const useCase = ({ profileRepository }) =>
usecase('Delete Profile', {
request: { indexer: String },
'Update the Profile': step(async ctx => {
await profileRepository.delete(ctx.req.indexer)
return Ok()
})
})when I transform it usingusecase2mutation(usecase, defaultResolver(usecase) I got this error:

}
it says that my usecase needs an response type,I tried use null but I got the same error.
Solution
I believe we can create an scalar Void type by default into the default schema, so we can use it when a usecase return nothing.
Inside useCaseValidator we can remove the line 16 const responseValidation = validate(useCase.responseSchema, defaultValidator). So when we get a usecase without response type into usecaseResponse2gql we can return Void
the final result will be somethinkg like
type Mutation {
deleteProfile(indexer: string): Void
}
here we have an clear explanation about the solution https://stackoverflow.com/a/61714123
