fatal compile error on chrome notebook.

[bdaly]

I'm using the Online editor with Chrome notebook, The code complied ok last friday when I prepped it for my students.  I tried it with my student today and got this error. Then tried it on my system and got the same error.

Error output:

I am having the same issue as of this morning.

Same problem in my class too. Really need it fixed for class tomorrow.

[ballscrewbob]

According to the team it was fixed.
Thanks for your reports.

Bob.

[Egibson356]

looks like it is working. Thanks.

[bdaly]

yes, fixed . Worked ok with my student yesterday. Thanks Team

I had an error today too, but seems slightly different - i don't see an error, just hanging when trying to upload. It just says "Busy" and progress bar rolls forever.

Here is my log output: https://gist.github.com/jywarren/50235371477b10d4e9815c4babef6e9d

I also briefly saw an error message that the compiler wasn't working. But the log seems to indicate that step was OK.

About 30m ago I was able to upload, and then it stopped working. Chromebook, with Arduino Micro - is there still an outage or a bug going on?

Thanks, all!

Could it especially have been the undefined in this line?
