Could not adapt the given Sling Model from neither request nor resource

[tgallant]

I am using AEM 6.5

I am trying to build a Translation Connector. I am using the AEM Translation Framework Bootstrap Connector https://github.com/Adobe-Marketing-Cloud/aem-translation-framework-bootstrap-connector

I can build and install the bundle to my local AEM instance using mvn clean install -PautoInstallPackage

After the bundles are installed I go to "Cloud Services" > "Translation Cloud Services" > "/conf/wknd-events/bootstrap-translation". When I try to create a Bootstrap Connector Configuration I get the following stacktrace. I expect the model to be able to be adapted from the SlingHTTPServletRequest and for the template to render the data.

Here is a pastebin with the full stacktrace https://pastebin.com/raw/Fh7CJPqG

This appears to be the most relevant part

SightlyException: org.apache.sling.api.SlingException: Cannot get DefaultSlingScript: Identifier com.adobe.granite.translation.connector.bootstrap.ui.models.BootStrapTranslationConnectorModel cannot be correctly instantiated by the Use API

java.lang.IllegalStateException: Could not adapt the given Sling Model from neither request nor resource: class com.adobe.granite.translation.connector.bootstrap.ui.models.BootStrapTranslationConnectorModel

Here is the model file

Does anyone have insights into how I can get this working?

Hi,

The issue is with the injected service, you need to use either @Deleted Account or @SlingObject to get request object.

e.g. https://github.com/arunpatidar02/com.aemlab.junitapp/blob/master/core/src/main/java/com/aemlab/junit/core/models/HelloWorldModel.java

@Model(adaptables = Resource.class)
public class HelloWorldModel {

    @ValueMapValue(name=PROPERTY_RESOURCE_TYPE, injectionStrategy=InjectionStrategy.OPTIONAL)
    @Default(values="No resourceType")
    protected String resourceType;

    @OSGiService
    private SlingSettingsService settings;
    @SlingObject
    private Resource currentResource;
    @SlingObject
    private ResourceResolver resourceResolver;

I am still facing this problem. I get the same stacktrace if I do that. In the code I pasted in the original message the SlingHTTPServletResponse was annotated with \@Self but it didn't show up in the code block for some reason.

Here is a link to that file in github where you can see the annotation https://github.com/lilt/aem-translation-framework-bootstrap-connector/blob/master/core/src/main/java...

I've also tried using SlingObject instead of Self. The stacktrace is the same in all of these instances. The full stacktrace is posted in the original message.

Hi,

I tried with your github code. For me Model works fine.

Though all the methods return null because of suffix is null in my test page.

I can see the componnet with this Model is rendering static content and for one of the method 

public String getFormPostPath() {
        return bootStrapConfigPath + '/' + JcrConstants.JCR_CONTENT;
    }

it return null/jcr:content

I was able to get this working.

The issue (sadly) was that I was using the wrong branch of the translation framework bootstrap connector repo.

The master branch of that repo is set up to work with the AEM Cloud Service SDK.

To use the translation framework bootstrap connector with AEM 6.5.0 you need to checkout the aem650 branch https://github.com/Adobe-Marketing-Cloud/aem-translation-framework-bootstrap-connector/tree/aem650

Once I was using the aem650 branch everything worked just as expected.

I've opened a PR to update this documentation in the repo https://github.com/Adobe-Marketing-Cloud/aem-translation-framework-bootstrap-connector/pull/16
