Using outputs() function and JSON Parse to read data from missing dynamic value in a Flow | Power Automate

I faced this issue lately and not sure if it’s a bug or something I might be missing. But, I couldn’t find anything in Dynamic Content in a Flow and I was not able to pick fields to use further in a Flow.

Not sure how many of you faced this since most fields you need are available in a Flow’s Dynamic Content part.

Scenario – Adaptive Cards for Teams issue

I had this one scenario in particular where the Adaptive Card I created for Microsoft Teams’ User sends back Response but the Dynamic Content doesn’t appear in the steps after the Card Step.

  1. See below that I’ve declared a Variable just to show that the Dynamic Content that should appear after the Adaptive Card.

  2. And if I press the Dynamic Content as shown above in Step #1, and minimize all the content, I don’t see the Teams’ Dynamic Content variables at all

  3. And the Adaptive Card didn’t return the below Outputs



    That’s when we should use outputs() function to read this data.

outputs() function

Here’s how you can use the Parse JSON action and outputs() method to read the Outputs of the step you want and then Parse JSON so that these can be picked as variables/dynamic values in steps following this –

  1. Take Parse JSON action from Data Operations in a Flow

  2. In that in Inputs, you can use Function on the Content field.

  3. And write outputs function as shown below –

    And the complete the function as below

    Explanation:
    MyCard is the name of the step of my AdaptiveCard I used. If the name of you step has spaces like “My User Adaptive Card”, then the function will look like outputs(‘My_User_Adaptive_Card’)[‘body’]

    body is written because if you see in the Outputs originally in the Scenario section above, all results are sent in body field of Outputs.

  4. Now, since you don’t know the Schema, just put a “{}” so that you can Save the step. (This is required)

  5. Run the Flow once and collect the Outputs from this ‘Parse JSON 2’ step as shown above.
    Copy the Outputs

  6. Now, open the same Parse JSON 2 step which you created. And click on Generate from sample

  7. And paste the schema in the box.

  8. Once done, schema will be generated like this.

  9. Now, this Parsed Outputs can be further used which will have the data from the Step which didn’t yield Dynamic Content
    Example, I’ll create a variable to show Dynamic Content that can pop-up

  10. It’ll show all the fields from the Card in the Parse JSON 2 outputs


    And that solves the problem!!

    Original Microsoft Documentation on the same is: https://docs.microsoft.com/en-us/azure/logic-apps/workflow-definition-language-functions-reference#outputs?WT.mc_id=DX-MVP-5003911

Using triggerBody() / triggerOutput() to read CDS trigger metadata attributes in a Flow | Power Automate

Now, for all the newbies working with Common Data Service (Current Environment) connector face a little constraint in order to read certain fields which are NOT in the list of the Dynamic Content of the CDS connector itself.

Scenario

Let’s say you want to read this field from the Body / Outputs of the CDS trigger in a Flow in Power Automate

Attributes (or rather supporting metadata) won’t be accessible directly since it’s not from the context of the CDS connector itself like you see for other fields as below –

Flow

In this example, here’s how our Flow will look like.

We’ll declare 2 variables after the CDS connector with Create or Update trigger on Accounts entity and how we can work with the results.

Reading from triggerBody()

When to use triggerBody() ? – When you want to fetch attributes from the body of the trigger.

Here’s how you can use triggerBody() function to read ‘RunAsSystemUserId’ from the outputs of CDS connector.

  1. Let’s say you have a variable declared to store your results. Let’s call it Trigger Body. Click on the fx sign to enter the formula

  2. Now, in the formula, enter triggerBody()?[‘RunAsSystemUserId’]. triggerBody() is a method to you’ll find it in auto-complete

  3. And the variable will look like this

Result of triggerBody() will be as below

Reading from triggerOutputs()

When to use triggerOutputs() ? – Whenever you need to access anything from within the body as well as some info from the header as well as shown in the 2nd screenshot in step #2 below.

Here’s how you can use triggerOutputs() funtion to read ‘RunAsSystemUserId’ from the outputs of CDS connector

  1. Let’s say you have a variable declared to store your results. Let’s call it Trigger Output. Click on the fx sign to enter the formula


  2. Now, in the formula, enter triggerOutputs()?[‘body/RunAsSystemUserId’]. triggerOutputs() is a method to you’ll find it in auto-complete.


    The reason this we write “body/RunAsSystemUserId” is because in the JSON structure of the complete Outputs of the CDS Connector, you’ll see that RunAsSystemUserId attribute lies inside body in the JSON.
    Whereas in terms of triggerBody() above, we are reading attributes from the “body” itself.

Result of triggerOutputs() will be as below

Hope this was useful!
