1. When I type something in the notebook and hit run. At least I think
that is when I get the error. It may happen when selecting the interpreter for
the notebook.
2. Yes
3. Running TO_UPPER('foo')
4. no, I get this for every statement I run.
Also, I don't get %stellar for the prompt like your screenshots
5.
- I set the interpreter through the dropdown not by typing %stellar
- I didn't have to 'create' the stellar interpreter after starting, there
was already an entry, I think from the site config
