How do I write to a text file using JSS?

Question

I am currently console logging info from my application and I would like to send it to a textfile.

var logFile = new File("/Docs/Logs/logFile.txt");

logFile.writeText("blahblahblah") and logFile.appendText("blahblahblah") gives me an exception: NotStreamableException.

I just tried this and it worked fine, although that was with version 12.  I don't have a version 11 installation handy right now.  Have you had a look at the logs to see if there are any clues as to why this is happening?  Does /Docs/Logs exist?

Yes the folder and text file do exist in the right locations.

I installed 11.0.6 and tried your code.  It worked fine again.  I ran the code in a process trigger that triggered on a successful login.  Where are you running it?  Is it in a process trigger, an extension or in a web-app?  Please be as specific as you can so that I have a better chance of replicating the problem.  If you'd like to include confidential information then you can open a help-desk ticket at enterprisedt.com/help.  I'll reply to you from there.
