How to use the @vtex/api.ResolverError function in @vtex/api

try {
      const { filename, encoding, mimetype } = file
      const headers = {
        'Content-Type': mimetype,

        }
      )
    } catch (e) {
      const status = e.statusCode || path(['response', 'status'], e) || 500
      throw new ResolverError(e, status)
    }
  }

    const session = currentSession as SessionFields

    if (!session || !session.id) {

    }

      : null
  })
}
