Uploading image to sharepoint

[philkky12]

I am following a tutorial to upload the base64 of a file uploaded from a PowerApp in to SharePoint using the create file automation. When I trigger the flow I get the following reason for failure:

Unable to process template language expressions in action 'Create_file' inputs at line '1' and column '8013': 'The template language function 'base64ToBinary' was invoked with a parameter that is not valid. The value cannot be decoded from base64 representation.'.

I have checked the expression (base64ToBinary(triggerBody()['Createfile_FileContent'])) and its exactly how the tutorial shows

Hi @philkky12 :

I've made a test but did not encountered the problem you mentioned.Here is my test for your reference:

Do you want to upload the photo taken over the phone to the SharePoint library?

If so,I've made a test  for your reference:
1\Add a camera control(Camera1)

2\Create a flow('PowerAppV2->Compose,Createfile')

/*This flow's trigger is PowerAppV2*/

3\Add a button and set it's OnSelect property to:

Set(Thepic,JSON(Camera1.Photo,JSONFormat.IncludeBinaryData));
Set(Base64Only,Mid(Thepic,Find(",",Thepic)+1,Len(Thepic)-Find(",",Thepic)-1));
'PowerAppV2->Compose,Createfile'.Run("ThePic.jpg",Base64Only)

TheResult

I think these links will help you a lot:

Store photo on Sharepoint

Getting pics to SharePoint from PowerApps is getting easier…
