Thank you, @kaloyankrastev, for contributing to the dotnet/dotnet-api-docs repo and adding the missing exception information. I've suggested a slight change to one of the exception conditions.

If you're planning to open a PR to address a problem you've noticed in the documentation, the extra step of creating an issue before hand is not necessary; you can just submit the PR.

Again, thanks for your contribution. We appreciate it.

Hi @rpetrusha,
thanks for having time looking at my pull request. Your suggestion makes perfect sense and I directly committed it, but there is back end engine exception in one of the build tasks. I can not find a proper way to retry the checks. Should I make a a commit with a dummy change in order to trigger the checks?

Again, thanks for taking my suggestions into account!

Try closing/reopening pull request, it should trigger build.

Thanks for making the additional change, @kaloyankrastev. Your closing and reopening your PR did trigger a new build, which looks good. I'll approve and merge now. The changes should be live on docs.microsoft.com in the next day or two.
