Improve error messages for Linux and Mac

[tobiasdiez]

With #404 now a detailed error page is displayed in case something went wrong with the "native messaging" to JabRef.

I've tested in Firefox and Chrome on Windows. However, it is not yet tested on Mac and Linux. Help for this is very much appreciated.

What you can do to help:

• For each step outlined in the manual installation instructions at https://docs.jabref.org/collect/jabref-browser-extension#installation-and-configuration, do the following:
  • Break what is written there (e.g. rename the org.jabref.jabref.json)
  • Try to import a webpage into JabRef. This should fail now and the error page should show.
  • Check if the instructions on the error page are pointing to the right issue (in the example above, they should tell you to check the path of the json file)
  • If that's not the case, please comment here with what you did, what the exception message was and what you would have expected.

Thanks a lot for your help!

Looks good @tobiasdiez!
I'll test it as soon as possible.

Works for me.

shouldn't it be :

No such native application org.jabref.jabref .json

Thanks, this is helpful. The error message should indeed give a list of possible causes and how to fix them (as in the first screenshot above, which is from the windows version). So here you changed the name of the json file?

What error is reported if you change the path variable to a non-existing path in the org.jabref.jabref.json file?

Yep, in the above example, I have changed the name of the JSON file. I get the same screen when changing the path.
