Posted on by IV-08040538-0

Hi, sorry ,english is not my first language.

I need to developed a flow as part of a proyect, which allows me to upload files by creating a new folder for each new form A submitted, and gives back:

- A new element A of a list

- A new folder (with it's attachments) in a document library

- The link of the folder as part of the element A of the list

The actual flow creates the folder and it's attachments but I can't submit the form or give the link back.

The code for my button is as follows:

ForAll(DataCardValue10_3.Attachments;'PowerAppV2->Crearnuevacarpeta'.Run(DataCardValue6_1.Text;ThisRecord.Name;
{name:ThisRecord.Name;contentBytes:ThisRecord.Value}))
 
In Attachments of this question is the image of the power apps flow I developed.
 
Please help¡¡¡¡¡¡

Right now your issue is that you’re calling the flow inside ForAll, so it runs once per file. That breaks the response and your form submission
You should call the flow only once and pass all attachments together. Use something like this:

Set( varResponse, 'PowerAppV2->Crearnuevacarpeta'.Run( DataCardValue6_1.Text, DataCardValue10_3.Attachments ) ); SubmitForm(FormA);

Then fix the flow:

In Power Apps (V2) trigger, make the file input allow multiple files

Use Apply to each to create files in the folder

At the end, return the folder link with Respond to a Power App or flow

That’s it — one call, flow does everything, and returns one link.

Hi @IV-08040538-0,

If you are patching multiple attachments here, you need the structure below, however if so, you cannot set a Variable inside a ForAll. It would be possible to do a Collection of multiple returned values, but I don't think that is what you are doing.
ForAll( DataCardValue10_3.Attachments As _Attach; Collect( colFiles; 'PowerAppV2->Crearnuevacarpeta'.Run( DataCardValue6_1.Text; _Attach.Name; { file: { name: _Attach.Name; contentBytes: _Attach.Value } } ).file ) )

If only one attachment - which I suspect is correct
UpdateContext( { varFile: 'PowerAppV2->Crearnuevacarpeta'.Run( DataCardValue6_1.Text; First(DataCardValue10_3.Attachments).Name; { file: { name: _First(DataCardValue10_3.Attachments).Name; contentBytes: First(DataCardValue10_3.Attachments).Value } } ).file } )

then use varFile for whatever you want to after that

or a simpler version

With( {_Attach: First(DataCardValue10_3.Attachments)}; UpdateContext( { varFile: 'PowerAppV2->Crearnuevacarpeta'.Run( DataCardValue6_1.Text; _ _Attach.Name; { file: { name: _Attach.Name; contentBytes: _Attach.Value } } ).file } ))

Also it is good to set the MaxAttachments of the attachment control to 1 for a single file requirement. You also might consider using another name for the returned value in the Flow other then file (which is could conflict)
