Problem with accessing JSON from form recognizer

(0) ShareShare
ReportReport
Posted on by Microsoft Employee

I want to build an app that identifies text fields in pdfs for which I have a well-trained custom azure model 

 

Custom azure model: https://docs.microsoft.com/en-us/azure/cognitive-services/form-recognizer/overview?WT.mc_id=gaicovt-event-gaic&tabs=v2-1#custom-models

 

On the https://make.powerapps.com/ website I created a "Flow" which asks for feedback for a document to analyze.

It's feedback formated in JSON is all well but all my attempts to put the JSON into a collector for it to be used by other parts of my application have so far failed.

 

I actually orientated myself heavily on this guy (https://www.youtube.com/watch?v=Kjb-Hnt_GpY) but with the difference of using unlabeled custom models. I fail to reproduce timestamp 14:46 and the seconds following that.

 

Weird facts:

 

1. The only thing my Collections tab has is this weird "image" tab (attached)

2. I know that the my flow of my API request sequence that the clearCollect Method does not seem to fire up the LieferscheinScan sequence at all. It only gets triggered when i directly put this in: LieferscheinScan.Run(UploadedImage1.Image, JSONFormat.IncludeBinaryData))

 

So it stands to reason that this guy from the aforementioned video worked on an older version of the powerapps meaning that clearCollect does not work how i think it is. 

 

Can so plz help me or show in the (specific) direction in the documentation of where to look

    @Anonymous ,

     The flow I created using this method that it will return the JSON result within 32 seconds whereby the user can't wait and accept.
