Hi all,

As I follow the Learning Journey https://learning.sap.com/learning-journey/developing-with-sap-integration-suite/creating-an-api-base... and do the hands-on in trial (us10), I cannot connect to the API Provider, hence cannot get 200 from API Proxy, Product and finally the Application created on  API Business Hub Enterprise (but the Open Connector is fine)

The error message is :

System is up and reachable. However, the ping check responded with code : 404; Message : Not Found

Can anyone help me?

Hi @Sidney,

could you please describe a bit more in detail, which steps you have performed successfully and at which step  (task + step + substep) you get stuck? Which "ping check" do you mean? The exercise instructions do not mention a ping check as such.

Thanks and best regards,

Jannes

Hi @jannes_schofeld.

I get the same error.

On the steps that I configure the Open Connectors tile, when I try out the process "GET /channels" or "POST /channels/{channelId}/messages", everything works fine and the retuned code is 200.

In the next step, on the API Management tile, I create the API Provider (Slack_Workspace_for_Orders), save it and click "Test Connection" button. (Yes, you are right, this last step not exist). Here I get the same error mentioned by @Sidney.

But I ignore this error and follow with the nexts steps:
- Create API, save API and deploy API (steps k to u).

After that I test the API Proxy (Task 5) and here I get another error:
On the "Test" icon I select "Slack_v1", select the GET radio button, select the URL that ends with "/v1/Slack/channels" on listbox and click "Send" button at the bottom of the page (steps a to e).

This is the error:

I believe that both errors are related.

Hi both,

Thank you for your answers!

I finished:

- set up in Slack side,

- create Open Connector instance in SAP Integration,

- test the instance,

- and then use the Organization Secret and User Secret to create API Provider in API Management (when the following steps won't work I went back here and test the connection and got the error message I posted in the question)

- create API (from the API provider) "Slack_v"

- tested it as taught in the Learning Journey "Developing with SAP Integration Suite" (unit 2 > lesson 4 > Task 5: Test the API Proxy ), but got error message: 

Unable to fetch response

Hi @Sidney,

can you double check, that when creating the API provider, you selected the correct region (US East (VA) - Trial) in your case? I have performed all the steps myself, also using a Trial Account in the US East region. For me it worked fine. An error message when testing the connection in the API provider is fine, because you are not calling any specific endpoint, thus the API might not know how to respond. But the message "System is up and reachable" is a good sign at that point.

Also, did the deployment of the API go through?

Apart from that, it does sometimes help to have opened every capability of the SAP Integration Suite at least once, so all of the necessary initial setup steps in the trial setup have been performed. For that, when you are in the SAP Integration Suite Home / Lobby, select Manage Capabilities. You will see the overview of all your activated capabilities. Scroll through the dialog and open each link at least once, in order to initialize the respective capabilities.

Best regards,

Jannes

Hi Jannes, today I openned the API Portal and re-test the API and it magically worked. I also tested them in API Business Hub Enterprise and suceeded. For the creation and deployment of the API and products, I failed once and them succeeded. I didn't change anything, so I guess it was the unstability of trial environment? Anyway I am continuing the hands-on. Thank you so much for your help!
