Thought I had this nailed, but no. The files aren't opening in the library, even though they show created as a .jpg and .png

Formula in button -
UploadEventDocumentsFlow.Run(Label15.Text,Subtitle2_20.Text &" - "& Subtitle2_18.Text,
{ file: {
contentBytes: First(Client_Attachments_Control_2.Attachments).Value,
name: Label15.Text & ".jpg"
}
});

When I try to open -

And when I download and try to open -

Are you using the new designer in Power Automate to build the flow? There have been issues when working with file content with that designer. It tries to add an additional base64() function to the content that isn't necessary. If you are using the new designer switch to the legacy designer and try again.

Old version. Just went back in to check.

Formula -
UploadEventDocumentsFlow.Run(Label15.Text,Subtitle2_20.Text &" - "& Subtitle2_18.Text,
{ file: {
contentBytes: First(Client_Attachments_Control_2.Attachments).Value,
name: Label15.Text & ".jpg"
}
});

@Phineas ,

Responding here as you have asked this question as part of two other threads I have responded to. You appear to be defining a folder path without using Create Folder to ensure it exists.

Interesting, in my original test everything (I assumed) worked fine. The folder was created, the file was created and did open.

And when I doubled back to upload another file for the same person the (sub)-file was created in the same 'main' folder, as if flow new the folder had already been created and just added the new file.

Is that even possible with my flow as currently constructed?

That works with OneDrive, but I have always needed to create folders in SharePoint.

But the flow created the folder, as shown, yes?

Is it your assertion that what I want to do is not doable using Power Apps V2?

@Phineas ,

No - you just have use Create New Folder - the Flow below is one of my older Prod Items using Power Apps V1, but that part is not relevant to the folder issue

Just did a test.

My current configuration, first run creates and names the folder and creates and places the file.

Second run creates the the files and places it in the previously created folder.

Not if you send the second new folder as the parameter in the second flow.

I don't understand.

My flow create the first folder and added the file.

Then it added another file to that same folder.

I changed the individual. The flow created a new
folder with that file.

I picked another file, the flow added that second
file to the second folder.

Everything is working. My only issue is I can't open
the files. Something in my flow/formula is not createing
these files in a way that allows them to be opened.

Thoughts?
