[BUG]: client.last_response is nil when workflow_dispatch is called on a non-existent workflow

[itskingori]

What happened?

When you call workflow_dispatch with the workflow-id of a non-existent workflow like so ...

begin
  options = { inputs: { environment: 'production' } }
  client = Octokit::Client.new access_token: access_token
  client.workflow_dispatch repository_uid, "deploy-nonexistent.yml", ref, options
  response = client.last_response
  response_status = response.status
rescue Octokit::NotFound, Octokit::UnprocessableEntity => e
  response_body = JSON.parse(e.response_body)
  response_status = e.response_status
end

You'd expect Octokit::NotFound to be raised but instead client.last_response is set to nil. I recorded the HTTP interaction using VCR and it does return a 404 Not Found, it seems the client is the one that's not parsing the response correctly? 😕

Obviously I can check for nil and handle it but it does seem to be an awkward design. If it was a 204 No Content maybe nil would make sense? 🤔 Something along the lines of ... it's because this method returns a boolean response and so a nil return is a way of saying there's an error. If return:

• true - it worked, dispatched!
• `false - it didn't worked, not dispatched!
• nil - something went wrong?

The odd thing is that when true, you do get a response in client.last_response. I don't know how to get it to have a false return for me to test what I would get there. Anyway, bug maybe? 🤷🏽‍♂️
