Unhandled exception

[ArtFlag]

Hi and thanks for this tool, it seems useful!

Env

• MacOs Mojave
• Dart and Linkcheck installed as recommended on the repo's readme.
• Webserver started with npm http-server (if that matters)

Problem

I'm running a local webserver with 4 folders at the root, and my index file. I expect the whole server to contain around 10 broken link (tested with other tools).

When I check with linkcheck, I get the following output:

Crawling: 2Unhandled exception:

(repeat the same exception)

But the CLI still runs! After waiting a couple of minutes, I get :

Errors. Checked 4892 links, 161 destination URLs (82 ignored), 93 have errors, 0 have warnings.

Which is not correct, but... it runs.

Any idea?

Having the same err.

Hi, sorry for not seeing this earlier. Could you please upgrade to latest (2.0.8) and try again? Please also use linkcheck --debug <url> and paste the whole output (or at least until the error). You might want to sanitize it in case you're crawling some secret/PII URLs - the debug output will have them all.
