Having the same issue with the same traceback at first attempt to start up Hydrogen (first line of shift + enter code).

idanrichman commented 5 years ago

i found out now that when i uncheck the "Extend Executable Code [experimental] the problems disappears

alextruesdale commented 5 years ago

Excellent, thank you. I suppose that means now that that "extend executable code" option is not required for multi-line functions to work?

kylebarron commented 5 years ago

I haven't looked into why this bug is happening (and it doesn't happen for me) but with the extend option turned off, the normal Hydrogen setting is applied, which means that any code block will run completely as long as the following lines are indented.
