问题
I keep failing to knit a github_document because of the error shown below. A solution to avoid this was provided in this question for html_document. But that argument is not available for github_document, and so I am wondering if there is another solution to avoid this error.
Error details:

The above reverts back to the old default before they moved over to CodeCogs
https://github.com/jgm/pandoc/pull/3142/files
I don't know what the issue with CodeCogs is, but it may have to do with not providing a Link Back.

The following works. But it didn't work earlier, perhaps there was an issue with the site.
