I am trying to do the same thing but having an issue in flow execution with error message in dataUriToBinary() method as following
"InvalidTemplate. Unable to process template language expressions in action 'Create_file' inputs at line '1' and column '1995': 'The template language function 'dataUriToBinary' expects its parameter to be formatted as a valid data URI. The provided value 'appres://blobmanager/7270bfce54874fcd830756ba77f58d59/5' was not formatted correctly."
I am following exact steps from the YouTube tutorial video but it seems for the PenInput.Image only returns the image's blob storage address instead of the URI stream. Could you please help me to identify what am I doing wrong there.
Check on these blog entries from John Liu that will give you the exact workaround you need:
I tried the second link as a solution changing the Picture Control to Pen Input Control, and worked just the same. In the solution he used Microsoft Flow, so when creating my own flow I used the actions "Create item" and "Add attachment" instead of creating a file in document library as he indicated in the steps and it worked awesomely 😄
Hope it helps!
For the PenInput, on collect(), what is LocalImage?
On my code for the peninput image capture, I wrote
But it gives me an error saying I need a collection instead of the datacardvalue8 and peninput1.image says "expected a record or table value"
A new easy and multi-purpose solution to save pen-input to Sharepoint is found thanks to Shane Young, utilizing the addition of a PowerApps Json functionality added on 02/05/2019.
The Short description on how to make this work is to save the pen input image in a JSON format asking the JSON function to include Binary Data:
Set( PenVar, JSON( PenInput1.Image,JSONFormat.IncludeBinaryData ) );
