https://github.com/NV/chrome-devtools-autosave stopped working in Chrome Canary. chrome.extension.sendRequest seems to cause the error, but the error message doesn’t give me a clue:

1. Error in event handler for 'undefined': Error: "onEvent" can only be used in extension processes.

The first error message is apparently harmless (i.e. is not caused by
actual failure) and is fixed as of r123230 (see
http://crbug.com/114583)

As of the second one, it looks bad, but I can't reproduce this with
either ToT or 19.0.1050.0 (knowing the particular version of your
canary might help).
I'm adding a test for this, just in case:

If this is still an issue for you, please file a bug on
http://crbug.com (having a reduction might help).

Best regards,
Andrey.

It seems to be fixed. Thanks for the response!
