Failed to deserialize argument data.  \r\n \r\n PAD

Posted on by zzz7 29
Hi,
 
I am calling up my PAD from Power Automate cloud, and I am passing in JSON. The JSON is valid when I run it on a validator.
 
The Power Automate cloud is throwing this error when trying to run my PAD:
    "code": "FlowArgumentError",
    "message": "Failed to deserialize argument data.  \r\n \r\n"
 
I had this working, and it broke four days ago.
 
I did recreate the PAD connection in my flow, and that did not work either.
 
Any ideas on what I should do? Is there more logging that I can get from PAD or do I have to remove all the line returns in the JSON?

    Hi @zzz7 

     

    Would it be possible to show the json structure?

     

    Also could you try to pass JSON as string and convert to custom object in power automate desktop?

    Here is the JSON without the data in it.

    The data is coming from my Dataverse database.

    I got it working. I had to limit the columns results using "Select columns" from dataverse, and that fixed it for me.

     

    Thank you for your help!
