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 ?
