Hi there,

I am trying to upload a Audio File that is recorded by the user to sharepoint library. This is working for me as i am the creator of the app and sharepoint library. But when other user records the message and save, Flow fails. I have verified the permission and my users have access to create a file in the sharepoint library. All users have Contribute permission in sharepoint library.

Flow error message shows as :

Unable to process template language expressions in action 'Create_file' inputs at line '0' and column '0': 'The template language function 'base64ToBinary' was invoked with a parameter that is not valid. The value cannot be decoded from base64 representation.'.

When user creates a file the flow as below.

When i create a file, the flow looks good.

Can anyone please help what is wrong ?

Hi @venka91 ,

Can you please include (in Text) the flow run code, in particular the JSON code where you are converting the file and also the base64ToBinary expression from your Flow.

Hi @venka91 ,

I must have missed your post - I have tested a sound example here and have this OnStop and it works perfectly

With( { wJSON: With( { wJSONI: JSON( Self.Audio, JSONFormat.IncludeBinaryData ) }, Mid( wJSONI, Find( ",", wJSONI ) + 1, Len(wJSONI) - Find( ",", wJSONI ) - 1 ) ) }, StoreSound.Run( wJSON, "TestSound1.wav" ) )

then the Flow

Note you need to "Ask in Power Apps" in the Compose function first, delete that and replace with the code shown
