Thanks for your report!
Do you have message like this in console? Would you like to get warning somewhere else in UI?

[romgrk]

No, that's the problem, I don't even get a message in the console, which would be fine.
If you need me to provide additional details for debugging just send me the instructions.

Ok, something weird just happened. I tried to reproduce the issue on my home laptop (archlinux, node 10), and got the same result using the 1.0.18 version from npm.
Then, I installed ndb directly from this repository, tried it, and got a message in the console.
Then, I tried again with the npm version and got a message as well.

Not sure what happened, but I'll check if I can reproduce with my work setup (on monday).

Thanks for your report, I will close it for now. Feel free to reopen it if it still reproducible on your machine at work.

[romgrk]

Still able to reproduce (with the same file as above):

Thanks, could you tell what terminal do you use? Based on screenshot it does not look like regular bash :)

[romgrk]

Shell: zsh 5.2 (x86_64-ubuntu-linux-gnu)
Terminal: GNOME Terminal 3.24.2 Using VTE version 0.48.4 +GNUTLS -PCRE2

I get the same issue using regular bash:

Thanks! Couple more questions: could you open DevTools on ndb by pressing Ctrl + Shift + I and copy paste console output here if there anything and update to latest ndb version 1.0.20 and verify that it is still reproducible?

[romgrk]

ndb 1.0.18 console:

ndb 1.0.20:

Thanks! I finally can reproduce it locally and am working on fix.

It looks to me that the root of the issue is combination of "Pause on exception" toggle, "Blackbox anything outside working directory" checkbox from Settings and Node 8.

You can disable "Pause on exception" to get SyntaxError in console.
You can disable "Blackbox anything outside working directory" to get pause inside internal vm.js script.
You can update your node to 10 to get SyntaxError in console even when both features are enabled.

Unfortunately it is too late to fix Node 8, please use Node 10 if it is possible.
