It appears you have missed the keywords on your form layout on the code you shared.
Try this and check if you get any data on your local!integrationResponse and share here if you need help diagnosing this further

a!localVariables(
    local!integrationResponse,
    a!formLayout(
      contents:{
        a!richTextDisplayField(
        labelPosition: "COLLAPSED",
        value: {
          a!richTextItem(text:tostring(local!integrationResponse))
        }
      ),
      a!buttonArrayLayout(
        buttons: {
          a!buttonWidget(
            label: "Submit Test Data",
            style: "OUTLINE",
            saveInto: {
              rule!CreatePatientResource(
                givenName: "Susan",
                familyName: "James",
                gender: "Female",
                dateOfBirth: "1989-02-23",
                onSuccess: {
                  a!save(local!integrationResponse, fv!result)
                },
                onError: {
                  /*Handle HTTP error */
                  a!save(
                    local!integrationResponse,
                    fv!error.message
                  )
                }
              )
            }

As suggested, I tried to create a simple test-interface .... But I am trying to figure out how to display the result returned by the integration because I am getting the following errors

Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error at function a!richTextDisplayField [line 5]: A rich text item or rich text list item in a rich text display component [label=""] has an invalid value for "text". Text can only be of type date, date and time, decimal, rich text icon, integer, rich text item, text, time, or user. Received RichTextDisplayField.

So, my typical approach is, to reduce complexity when I am stuck. Build a separate test interface with just the minimum things. Then I suggest to save the whole API response to a local variable. Then drill into it, step by step. It is so easy to get this wrong.

RE: Parsing HTTP Response

The interface works - I don't see any error message.

Rochester ,

Your code looks good and I dont see any problem . Since you are getting the response from your headers after the integration to debug it will be worth capturing the whole response from fv!result to your local variable instead of indexing it right away and check if the response is indeed as you are expecting it to be.

What do you mean with

[quote userid="246616" url="~/discussions/f/integrations/35001/parsing-http-response/135561"]If I remove the highlighted line, it works[/quote]

What does work? Do you see any error message?

That line looks good for me.

Hello Naveen:

Here is the code.... If I remove the highlighted line, it works but I need the ID from the integration's response (see image from previous post).

In your code, in the onSuccess, I do not see that you try to fetch any data from the API call result.

Find here the documentation about how to call an integration.

https://docs.appian.com/suite/help/24.1/Call_an_Integration.html

Then, I suggest to create a very simplified test interface to make a root cause analysis easier.

Error:Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error:

This error appears to be more with how the data is being handled after your integration call.

Your code for calling the integration itself appears to be good.

If you could share the code for your interface that would help diagnose the problem

OK. And the other questions from my post?

When you configure that integration to "Usage: Modifies Data", you can only call it inside a saveInto or a Call Integration node in a process. And this is when the onSuccess and onError pop up.

RE: Parsing HTTP Response

Rochester — Thu, 16 May 2024 13:21:27 GMT

The onSuccess/onError was shown as rule-inputs when we selected "Override and define all error conditions" option.

This is the integration that we are trying to call and obtain results from.

RE: Parsing HTTP Response

Stefan Helzle — Thu, 16 May 2024 11:20:05 GMT

And what errors do you get?

For me, your code and your requirements do not match.

Where is this "onSuccess" coming from. Do you try to call an integration which you configured to "Modifies Data" just inside some expression code?
