We are implementing Actions on Google with Dialogflow fulfillment using the newly released Java/Kotlin API.
It's called Speech Bank
.
While going through the Account Linking process testing on the smartphone, the user is getting MalformedResponse error preventing the completion of the flow and consequent successful hand-off back to the regular flow.
The logs (detailed below) contain the MalformedResponse: Failed to parse Dialogflow response into AppResponse because of empty speech response
message, and the user receives Speech bank isn't responding right now. Try again soon.
message on her device.
Here's a bit more details on our setup:
The action is configured for Account Linking utilizing our own OAuth 2 compliant mock infrastructure.
There's a single intent (called RawText
) configured in Dialogflow, the rest of the interactions are to be taken care of by own internal application via its web hook.
Here's how the state machine is coded in Java so far:

QUESTION
I am working on a custom kubernetes controller, which creates kubernetes secrets based off some inputs. As part of this controller it is required to copy these secrets to multiple namespaces. Which it successfully does.
For e.g.
...ANSWER
Answered 2019-May-02 at 18:21Since the controller wasn't able to detect the changes from the object in other namespace, I tried to scan all the namespaces in the cluster and had the reconcile loop end with
return reconcile.Result{RequeueAfter: time.Duration(15) * time.Minute}, nil
to allow reconciliation every 15 minutes. The controller does respond to the events to the secrets created in the same namespace as the controller is running.
QUESTION
I have a table with 8 columns in my DB. I want to search all columns for at least one occurence of a String. After that first filtering is done, I want to filter this return for at least one occurence of another String in one specific column.
I have been doing all my filtering using derived methods and queries by example Spring Jpa. It seems that this filter I need is not possible through those ways. It looks that built queries is the only way to make it work, so I had to use a @Query annotation, and create a method, to implement that custom query. Although, it is returning an error I cant seem to find the solution. Also, I need the method to return a Page, and have a pageable as an argument.
Can you figure out why this @Query call is not working?
...ANSWER
Answered 2019-Apr-23 at 14:47I found an answer! I just needed to substitute the SELECT * for SELECT count(*). The countQuery variable is used to get a count of results.
QUESTION
Is it possible to make a repository exposed as rest resource via the @RepositoryRestResource
annoation Async? Or in other words, I want the save, find etc mehtods to be async and the ResponseEntityController
also process these as async calls?
If I simply mark the repository as sync my POST request fails because this method on ResponseEntityController
would not process async persist calls for a repository
ANSWER
Answered 2018-Nov-29 at 06:36The only way I've found is to stick to Spring Data JPA and write your own HATEOAS controllers returning CompletableFutrues which call Services that assemble HATEAOS Resource(s) from values returned by JPA repository. The controller to Service and Service to JPA repository calls can then be asynchronous using Thread pool executor or Concurrent executor etc.
QUESTION
I need to add additional business-logic for POST method. For now, I'm going to reuse the logic from RepositoryEntityController for getting and save the needed object.
...ANSWER
Answered 2018-Mar-27 at 09:47Spring Data REST emits its own events when working with entities:
- BeforeCreateEvent
- AfterCreateEvent
- BeforeSaveEvent
- AfterSaveEvent
- BeforeLinkSaveEvent
- AfterLinkSaveEvent
- BeforeDeleteEvent
- AfterDeleteEvent
You can listen to these events to add your additional business logic. For example, to perform something after the SDR creates a new User
(with POST method) or saves (updates) the existent User
(with PUT/PATCH methods), you can use such a handler:
