cannot create PyString with non-byte value

Hello, I am learning nodebox on a university course.

The phrase 'cannot create PyString with non-byte value' keeps popping up.

I don't know where it went wrong.

I tried reinstalling the program, but It couldn't solve the problem. The last time before saving everything worked, but now an error always appears. I sent the same file and dataset to another computer (Mac OS), and everything works there. But I use Windows.

Hi, sorry hear you’re having this problem. I don’t currently have access to a PC, but will try to help.

Does this error occur whenever you try to open any NodeBox file, only a particular file, or only when you render a particular node in that file? Does it occur with one dataset but not with another?

Please include a zipped copy of your NodeBox file and the dataset so that I may test it. If the data is confidential perhaps you could send a small subset of it (just enough to trigger the error).

I hope I can help!

Hi,

This looks like it has something to do with Unicode characters or spaces in your path. NodeBox sometimes has issues with non-western characters in the path, specifically on Windows.

What could you try: the NodeBox folder is in Users\your_username\AppData\Local\NodeBox. (I think). You could try copying this folder and moving it somewhere else (e.g. just your C drive) and then try double-clicking the app from there.

Let me know if that works!
Best,

F
