Uploading Audio File to SharePoint from Power Apps through Power Automate

Hi community, 

I have spent a lot time trying to resolve this issue, I hope you already resolved and can share the solution

I have created an app in order to save audio in the mobile ( i am using the multimedia resources included en power apps)

additionally I have created a flow in order to create the file in sharePoint (see below) 

Running the app from the PC it works, running it from the mobile I get errors 

"InvalidTemplate. Unable to process template language expressions in action 'Crear_archivo_2' inputs at line '1' and column '13375': 'The template language function 'Base64ToBinary' was invoked with a parameter that is not valid. The value cannot be decoded from base64 representation.'."

 

Trying to resolve the issue I have followed some youtube tutorial using base64ToBinary and toString funtions...  but not good outcome

I have recreated the flow, using the differente recommendations...but I got at the same end

 

Is there any special condition or consideration when I create the audio from mobile?

Hi,

 

So played out this scenario and it worked when saving as WebM:

Set(gblSharePointFileLink,UploadAudio.Run(Now() & ".WebM",JSON(Microphone1.Audio,IncludeBinaryData),"").sharepointfilelink)

One From Mobile and one from PC, both of which play:

So out of interest is the mobile device Apple or Android? I am using Android in my example.

I would imagine that it is because the format of the audio file coming from the mobile is not a valid DataURI perhaps? So it fails to do DataURI to Binary.

I would however try and parse JSON or do a compose like in the Flow example above. So we can at least confirm what type of media file it is coming through as. Or do you already know the extension?

Thanks

 

Henry

Replace in OnStop Mid(varJson,25,Len(varJson)-25) with Left(Last(Split(varJson,",")).Result,Len(Last(Split(varJson,",")).Result)-1). This is a more generic version that appears to work for other platforms.
