I have a PowerApp that connects to a Power Automate Flow. When an image is uploaded to the PowerApp the flow is triggered. The flow connects to a Form Recognizer API and I am trying to get the response back to PowerApps so I can use the data in the app. So essentially my flow is connected to the app, I can connect to the API in the flow, and everything is fine. Then I add a Response action to the flow and everything is still fine. When I add a schema to the Response action the flow disconnects from the PowerApp which I've gathered is normal. My issue is I cannot connect the flow back to the app even after the schema has changed and the flow is removed. I keep getting this error message:
Unable to add flow
There was a problem adding your service. Please try again later.

This is normally caused by some problem with the schema. For example, do you have any properties in the schema where there are multiple types or data values that might be null? Both of these can cause issues. I normally find that its a good practice to clean your data in the flow before sending it back to Power Apps. Using a combination of Data Select (to filter out unnecessary columns), filer array (to remove rows with null values) , and parse JSON to re-parse the new array of data before sending it back to Power Apps.

This is my schema, I've tried filtering and using the select action and I am still stuck, maybe I'm dumb but I cannot identify the issue with this
How did you get the schema? Did you generate it using the Generate schema from sample button? The first thing I noticed is that there are several required: sections. To the best of my knowledge Power Apps/Power Automate only allow one. I think you have more than one data set schema embedded here and I suspect that is the problem.
Hi @David59740 ,
ClearCollect(colName, FlowName.Run("JSON Data you want to convert to a collection"))
Thanks
Thanks for the response @Pstork1. Yes I am generating as sample from the results of the GET request and it is bringing back the before mentioned schema.
If its not sensitive information could you post a sample of the data you are getting back from the Get Request? I'll try to help with how to clean it up.
@Pstork1 I apologize for the format, the website would not let me upload since it exceeded the data limit.
Ok, I've got the sample data. What specific data/fields are you trying to get back to use in Power Apps?
MerchantName, MerchantAddress, MerchantPhoneNumber, Subtotal, Tax, Tip, Total TransactionDate, TransactionTime
And all confidence levels associated with each.
OK, let me play around with it a bit. I've made some progress. The problem is definitely related to the embedded schemas that are in the JSON that is returned. I was able to isolate and return the full 'documentResults' array as a collection. But drilling down into it gets blocked by the embedded schemas. I need to find a way to isolate the specific fields you want.
