Invoke web service parsing error in PAD

(0) ShareShare
ReportReport
Posted on by 2

I am new to PAD and am attempting to create a flow that mimics one I have previously created in Power Automate.  I have all of the settings the same (URL, method, custom headers, and body) and the flow runs correctly in PA but gives a parsing error in PAD.  

 

{"message": "Could not parse request body into json: Could not parse payload into json: Unexpected character (\'%\' (code 37)): expected a valid value (number, String, array, object, \'true\', \'false\' or \'null\')\n .....

 

In PAD, I am passing the request body as a variable before I invoke the web service, as shown here:

 

RequestBodyVar.PNG

For comparison, here is my PA flow:

I have also tried to pass the request body directly in the "invoke web service" step instead of as a variable, and I get the same parsing error.

 

Is there a guide on how the JSON is supposed to be formatted in PAD?

    Anyone?  Can someone post a screenshot of how they use the "invoke web service" feature and why it's different from using standard Power Automate?

    Hi @kweighall , 

     

    In PAD % is a reserved character.

    % --> %%

    Add one more % to escape the character. Something like this https://microsoft.com/test/%%12321%%
