Encountered an issue when calling the AI model while sending data in base64.

Hi,

I’m trying to create a cloud workflow that runs when a web service is invoked from PAD. PAD will send a PNG file converted to Base64 to the cloud workflow to call AI Builder, and then return the results back to PAD.

The problem is that when the flow uses the AI Builder action, I get the error: "Invalid input: Input parameters are invalid for your model."

I want to know how I can fix this issue.

    Hello,

    Convert the Base64 string from PAD into binary using base64ToBinary() before passing it to the AI Builder action.

    AI Builder only accepts binary file content, not raw Base64 text.
