Webcamera saving photo in app as png

Posted on by PeterOlding

I have an app in which users use their webcamera, been working fine but recently the app has been saving the file in the sharepoint list as a png file rather than jpg. The Power Automate flow then can't process the file. Anyone come across this and have a solution please.

Hi @PeterOlding,

You have control of the file name - whether it be in Power Apps or a Flow, the file extension you allocate will save the file type required - how are you currently naming it ?

Thanks for the reply

At the moment I put the image in a variable

Set(

PhotoFromImage,

JSON(

Image2.Image,

JSONFormat.IncludeBinaryData

)

);

Then in my patch statement place it in a sharepoint list

imgPicture: base64only,

For some users the image starts "data:image/png;base64,iVB" so I assume its a png image. What ever it is it causes my flow to fail with 'The template language function 'base64ToBinary' was invoked with a parameter that is not valid. The value cannot be decoded from base64 representation.'.

Hi @PeterOlding,

The image can certainly be saved as a JPG and you also do not need to use the JSON conversion when sending to a Flow - just send the file name and the content
YourFlowName.Run( "MyFile.jpg", Image2.Image )
