Possible to type out Dyanmic Content?

Hello, 

 

I'm very new to PowerAutomate so unsure of all it's capabilities. I'm curious if it's possible to type out Dynamic Content and use in a Apply to Each Action?

 

example: body('Parse_JSON')?['result']?['success']?['XXX-XXX']?['parameters']

 

Reason I ask is because I'm reading a JSON from an HTTP request. The JSON path unfortunately includes a variable that we push to the request but that means the Dynamic Content changes every request as well (ex: body('Parse_JSON')?['result']?['success']?['XXX-XXX']?['parameters']).

Seems like Power Automate doesn't change the path after every request; for example, if the first request uses '123-456' the Dynamic Content will include that '123-456' but if the next request we use '789-123' it doesn't work unless we go into the flow and remove the Dynamic Content and then re-add. 

 

I tried simply removing the Dynamic Content and then typing in the name (body('Parse_JSON')?['result']?['success']?['XXX-XXX']?['parameters']) in the Expression but it errored out with the following,

"The template validation failed: 'The repetition action(s) 'Apply_to_each' referenced by 'inputs' in action 'Select' are not defined in the template.'."

Is this a possible feature inside Power Automate? Thank you!!

Hi @abm

 

Yes, what you're saying makes perfect sense! So it doesn't perfectly solve my issue because it's not that there could be many different properties but just one property with different names. But thanks for that idea, will add to my tool kit 😁

 

I actually was able to figure out the answer to my question though, it IS possible to manually type out Dynamic Content. 

 

I had an HTTP response that gave the following data...

{

  "method": "fetch",
  "result": {
    "success": {
      "r6710a99-302r-42a8-9e04-944a406336a4": {
        "data": {

          .....

        }

      }

    }

  }

}

 

So the Schema for my Parse JSON had to look like the following...

{
    "type""object",
    "properties": {
        "method": {
            "type""string"
        },
        "result": {
            "type""object",
            "properties": {
                "success": {
                    "type""object",
                    "properties": {
                        "r6710a99-302r-42a8-9e04-944a406336a4": {
                            "type""object",
                            "properties": {
                                "data": {
                                    ....
                                }
                            }
                        }
                    }
                }
            }
        }
    }
}
 
I was worried that since my "r6710a99-302r-42a8-9e04-944a406336a4" changes everytime, my schema will break. But looking at this stack overflow article, looks like it's still possible. 
 
So I kept the schema and then did a compose right after using a text to describe my dynamic content,
body('Parse_JSON')?['result']?['success']?['r6710a99-302r-42a8-9e04-944a406336a4']?['data']
body('Parse_JSON')?['result']?['success']?[variables('inputID')]?['data']
 
And it worked beautifully! Now when I inputted a new '#####-###...' it's flexible and dynamic!

Hi @Jakeapril 

 

From the above my understanding is you have a HTTP request and the response values are dynamic. If you using Parse JSON schema it works with a fixed schema set. Do you know all the possible values returned from the HTTP request. The extend the schema with all the values. If you don't know the schema set and its fully dynamic its not possible to extract using Parse JSON step.

Thanks

Hi @abm, thank you for the reply! And thanks for all the help you give on the forum, I've been learning a lot from your responses on other posts 😄

 

Ah you may be right, I do not fully know the Schema set as it is dependent on what is returned from the HTTP request. I assume if you don't know the full Schema set, it's not possible to extract all data?

 

For example, right now my Schema set is:

{
    "type": "object",
    "properties": {
        "method": {
            "type": "string"
        },
        "result": {
            "type": "object",
            "properties": {
                "success": {
                    "type": "object",
                    "properties": {
                        "f6710b99-302e-41a8-9e06-976ab06036f4": {
                            "type": "object",
                            "properties": {
                                ....
                            }
                        }
                    }
                }
            }
        }
    }
}

I can't just use the following, omitting the dynamic info in the schema...

{
    "type": "object",
    "properties": {
        "method": {
            "type": "string"
        },
        "result": {
            "type": "object",
            "properties": {
                "success": {
                    "type": "object",
                    "properties": {
                       ... missing info here ...
                    }
                }
            }
        }
    }
}

 

I assume I can't use the above and still pull out that last "properties" data from the first code snippet?

 

Thank you!

Hi @Jakeapril 

 

Thanks for your reply.

 

Here is an example. 

 

Sample Schema 1

 

{

"Name":"David",

"Age":23,

"PostCode":"LD3 4RT"

}

 

Here is another schema where Postcode is missing and new property called Employed is added.

 

Sample Schema 2

 

{

"Name":"David",

"Age":23,

"Employed":"Yes"

}

 

So for the above you could generate a JSON schema like using the below data. Here I know all the possible outcome of the data in different situations.  Hence I generated the data manually and generated the Parse JSON schema.

 

{

"Name":"David",

"Age":23,

"PostCode":"LD3 4RT",

"Employed":"Yes"

}

 

This way if the info is missing it will return you blank but you need to know the full combinations of the schema.

 

Hope it make sense.

Hi @Jakeapril 

 

That's good to hear. 

 

So if you use question mark its optional.  If you don't use question mark between the properties then it expects that in the schema.

 

body('Parse_JSON')?['result']?['success']?[variables('inputID')]?['data']

 

Thanks for the update.
