Base64 to file object in service

I saw in a previous thread about base64 to image here that I could use custom file content to map base64 to an image. I create it in a database connected source, however since this approach uses Blob I get an error when creating it, which I understand is expected behavior.

Is there any other way to create an image object file from Base64 in services?

Hi, I have sent you a DM about this!
