Hi Guys, I have an adaptive card which is giving a table value of the some states. I want to use the concat function to join the table values into a string and pass it into a PA flows. While I had achieved something similar using the classic version of PVA and Botframework composer I am unable to do so in the unified canvas. I have the array which is giving the following outputs.
How do I join the state1 table values together into a PA flows. I cannot pass a table variable into the PA flows so need to convert it into a string first. Please advise. I did try using the following powerfx fornula Concat(Topic.State1,ThisRecord.Value,",") or tried to use ForAll functions to loop through all the values but am unable to find a solution to join these values together. Help will be appreciated. Thanks!
The table should be the equivalent of a collection in Power Apps. Have you tried using the PowerFX JSON() function to generate a JSON string that you can send to the flow? Then use a Parse JSON in the flow to read the values.
@Pstork1 unfortunately I cannot seem to use the Json function in the unified canvas. The only formula I can use is ParseJson which is expecting a string variable as input.
Not the ParseJson() function. Use the JSON() function. Then use a Parse JSON action in the flow. here's the documentation on the JSON function. JSON function in Power Apps - Power Platform | Microsoft Learn
@Pstork1 I am unable to use the JSON function as mentioned in my comments. Unified canvas does not recognize the function
Your previous screenshot was showing the ParseJSON() function. But I tested and you are correct that the JSON() function also isn't supported.
Take a look at the following video. There is now an advanced Step that can Parse JSON directly in PVA. That may help with your issue.

@Pstork1 Thank you for your reply and all your help. I went over the video but I am still unable to produce the desired outcome on my end. My current issue is I am not sure what the output format is for the adaptive card in the unified canvas. When I created this in the previous PVA version it generally gave a string output as per the adaptive card outputs as shown:
With the unified canvas since it is already segregating the data items into separate variables I am unable to determine the format of the output data from the adaptive card. I am still not sure how I can parse that array as a Json Object and how I can extract just the value of the arrays selected from the adaptive card. It is easier to use a some sort of Join/Concat function in PA or botframework composer to get this done however I am unable to figure out how to achieve this here. If you could give me some example of similar scenario for an array to string that will be great.
I;m not sure if this helps, but using the sample JSON from the video I was able to parse the items to a Table and then concat the table this way to get the name values
If you can get me a sample of what the output of the adaptive card looks like I can try to help you figure out the exact steps needed.
