How can I update nested fields using a Logic App

**Background:**
I'd like to perform an update on nested fields using the LogicApp

 

**This is what I did:**


1. Ran my query to fetch the documents I need

2. Create global variable that holds the array that I wish to 'update'

3. Run for each loop over the first query, parsed the JSON , create a for each loop for

all of the items in the Feedbacks array : 

 [   
{ "id" : "1234"}

 ]

4. Append the variable that I created with the current item in the loop

5. Finally update that original feedback array with the updated array that was created in the

   first variable dynamically.

"id":"1234"

"Features":

{

"id": "update me"

"state": "update me"

}

]

Error I have:

I suppose its placing the array



{

"id": "update me"
"state": "update me"

}

]

inside the

Feedbacks array []

When I am wanting  the items and array that the feedback id is pointing to to be updated within the feedback array, nested in the Features array.

 


For instance this is the feature container that holds the Feedbacks array (highlighted)

And within the Feedbacks array above, I am wanting to iterate within each of its ids and then update that Features array with what I provided in the variable

(I believe what needs to be updated is being placed in that initialize variable?)

 

 

Any advice or suggestion is greatly appreciated. I am a bit stuck on this.

Hi @jasmine2020 

 

 

Your second for each loop I can see you append to array and immediately create or update the document. Is that correct? I can see here your array is going to append 20 times and each time it is going to create or update operation?

Hi @abm 

 

I am not sure if I am doing this right. For every document in the Feedback array, I wish to loop over this and update the contents within it.

 

 

             Feedbacks: 

                        [

                               {

                                      "id":"1234"

                               }

                       

                              {

                                     "id":"5678"

                              }

                        ]

 

so for every document within this Feedbacks array, I wish to then update the nested fields within it

 

 

 Inside of the "id":"1234":

                  

 

                       "id":"1234"

                       "Features":

                                            [

                                             {

                                     

                                                "id": "i wish to update"

                                                "state": "i wish to update"   

                                             }

                                          [

 

 

I figured I can do a for each loop to iterate over the feedbacks document and then

use a variable to replace certain fields I need to update

Hi @jasmine2020 

 

Couple of issues we resolved

 

1. JSON schema validation failed due to null. We resolved this changing the parse schema validation to accept string or null.

2. Next we iterate the ID and extract the id value using another Parse JSON

 

Thanks
