A Big Thank U to the entire PowerApp Community

The question NOW for me, TO FLOW or NOT to FLOW, versus OFFICE365GROUPS.HTTPREQUEST connector

I have been using a flow for some time now with no issues. (see FIGURE B:1-4 below) From within my Power App the flow gets an attachment from Sharepoint List (A) attachment data card control within a form, and uploads to a SP Document Library (AB), at the same time from the SP list A, extracts the Product ID number value from the same Form was in, to the SP Doclib AB.

This method been working for a while now BUT until recently for some odd reason, been getting a JSON error message (below Fig A). I tried to wrap parameter text with value etc… restarted rebooted rewired , still issues….what is weird is EVEN though am getting the error message the flow runs successfully and the desired result is achieved. I just can't seem to shrug this error message off.

Fig A

After coming across the Office365GroupsHttpRequest Connector Thanks to @Reza Dorrani video, https://www.youtube.com/watch?v=n3mhe88BI34&t=790s

I found this method yielding improved results.

On a blank screen, On a button I put the code below in, which pulls from an attachment control (outside of the form).

(ForAll(DataCardValue12.Attachments,Office365Groups.HttpRequest("https://graph.microsoft.com/v1.0/sites/......./root:/"&ThisRecord.Name&":/content","PUT",ThisRecord.Value)))

This solved the error issue and 1 less flow to call. But My problem is I cannot seem to find a combination of the above code with a patch or collection to get the desired result (See Figure 4 below ) i.e. Product ID Value from a selected gallery item SP list A, to the uploaded attachment column in the SP doc lib AB. all in one shot.

Is it possible to use office365groups.httprequest connector with a Patch or Collection, or maybe a combination with flow in a Power Apps environment to achieve desired results ?

FIGURE B below 1-4

Within my Form , OnSuccess I have a FlowAddanitemtoSPandDocLib.Run(Varlastitem.ID) set to run when an attachment is added, which then triggers flow , and pulls the Product ID number variable with it to the Doc Lib AB

4 - Current result of flow

Hi @Shazam007

Is the ParseJSON/Untyped feature enabled for your App?

There has been a change to this feature recently that results in most responses throwing this error.

Could you try casting the flow results returned to a specific type using JSON() function as a wrapper? I know there's a thread in the experimental section for feedback so it might be worth putting in some info there and they do mention about casting types:

Ok, as I mentioned, you'll need to give your feedback around this issue in the thread that covers this experimental feature as there are no documented fixes or workarounds for this kind of thing as it's still an experimental feature:

Hi

I managed to find a solution for the problem - to land documents (without using a flow) from an attachment control to document library with some meta data from Sharepoint List ... see steps added code highlighted in red.

ForAll(DataCardValue52.Attachments,Office365Groups.HttpRequest(" https://graph.microsoft.com/v1.0/sites/..../root:/"&ThisRecord.Name&":/content","PUT",ThisRecord.Value
Refresh(DocLibAB);
ClearCollect(collastdoclib,Last(DocLibAB));
ForAll(collastdoclib,Patch(DocLibAB,LookUp(DocLibAB,ID=collastdoclib[@ID]),{ProdId2Num:varproditem2.ID}))
*Note*
ProdId2Num is column name within SP Doc lib AB where the value from the SP list A will land
varproditem2.ID is the prod SP LIST ID value from SP list A. This variable was initiated and set when clicked a button within a gallery list item of SP list A. The Button had following on the onselect; Set(varproditem2,thisitem);Navigate(newuploaddoclib)

Steps
Watch this excellent video by Reza Dorrani to understand the first forall part - Power Apps DIRECTLY upload files to SharePoint Document Library | GRAPH API - https://youtu.be/n3mhe88BI34

1.After the first FOR ALL I added a new line; REFERESH of the doc library
2.COLLECTION of that last or latest doclib record just added
3.then a new FORALL to MATCH ID's of Collection with Last Doc Lib AB record ID
4.PATCH the variable containing the Sharepoint list ID value to the Doc Lib AB Column (this is the relational table part wanted to achieve)

After a few test runs Worked... No need for the flow
Thanks
