is there a way using javascript compatibility code to save a txt type file with some text? ... I'm using maestro ...
I have no idea how maestro is using graal-js. There are no standard JavaScript built-ins for file writing. If maestro allows you to use Java-JavaScript interoperability then you can save the file using Java methods:
var line = "Hello, world!";
java.nio.file.Files.write(new java.io.File("world.txt").toPath(), java.util.List.of(line), java.nio.charset.StandardCharsets.UTF_8);
If general Java-JavaScript interoperability is not allowed by maestro and this use-case should be supported then it is up to maestro to provide the corresponding function/built-in.
Return error for Blob:
Blob is Web API. graal-js is not a browser. So, we do not support Blob (and other Web APIs).

It means that java is undefined, in other words, that Java-JavaScript interoperability is not available in your context. As I wrote above, if you think that your use-case (writing to a file) should be supported by maestro then you should ask there how to do it. The only support that graal-js provides in this area is through Java-JavaScript interoperability.
