Flow returning null when file path is expected but only on one file create action

[lmheimendinger]

I created a simple flow that is invoked from Power Apps.  Here's a brief verbal description:

• Three parameters from PA - file category as integer, file name, file contents
• Integer is 1 to save a pen input, 2 to save a camera photo
• File name uses customer info plus date for unique name plus .jpg
• file input data from pen input or camera

The flow correctly creates a file in one of two different picture libraries and is viewable, so that is not the problem.  

When the flow save the pen input (signature), it saves the image AND returns the file path. When it saves the photo, it saves the image but returns NULL as the file path. Can you suggest why this is happening?

Here is the flow steps for that

Here is the run data for a photo

and for the pen input

On the create file action for photo, you can see "path" has a correct value, but it is not returned
