How to attach camera image from PowerApp to Notes entity in Dynamics 365?

I want to save the image taken from the camera control in PowerApp in the Notes entity of Dynamics crm 365.


For this I have taken help of: 


In the compose action of the flow I have formula:-



The notes entity record is getting created with image as attachment. But I am getting below error when opening the image:-

"The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters."


Please help.

Hi @Ancy,

Could you please share a bit more about your scenario?

Do you want to pass an image captured via Camera control (within an app) to a flow, then attach it to Notes entity record?

I think there is something issue with the base64ToBinary() function within the formula that you mentioned. Please take a try with the dataUriToBinary() function instead of  base64ToBinary() function, then check if the issue is solved.

Please type the following formula within the Inputs field of the "Compose" action:


then check if the issue is solved.

Please also check the following blog for more details:
