Hi @marcus.rognes,
Thanks for your post. You can find the example you’re referring to here.
To make base64 encoding work as expected, the “Custom File Content Encoding” setting needs to be enabled manually on our side (see the last reply in your linked post). We’ve now activated it for your solution. If you refresh Create and have set everything up as shown in the example, it should work correctly.
Let us know if you still run into any issues!
