Invalid artifact URL with v1.2.9

Hi there

I saw that the invalid artifact url fix was backported into v1, however I'm still getting the Invalid artifact url message.

I'm using Github Enterprise Server 3.8.6

Could this be an error on my side, or some particular quirk with the 3.8 version?

Thanks in advance!

Run actions/deploy-pages@v1.2.9

Start at src/api-client.js:116, then follow the deployment flow through src/deployment.js:59 and src/index.js:30. Reproduce the failure on GitHub Enterprise Server 3.8.6 with actions/deploy-pages@v1.2.9 and compare the shown artifact URL with the backported fix. Done means the artifact URL is accepted or the incompatibility and required workaround are documented.
