After I posted the question, I realised my mistake 😅. I was using the pg gem in Ruby to run the SQL "SELECT encode('123\000\001', 'base64')", the double quotes ensure the `\0` will be interpreted as a null byte hence throwing the error. Sorry, my mistake!

I think it’s something in the former category, the example works fine:
How are you executing the example, via psql, another client or in some other way? Is the data perhaps being in some preprocessed along the way before it reaches postgres? If you copy/paste it in psql, does that work?
