I don’t know is this related or not, but the katex error is also masked

https://github.com/wenerme/wener/actions/runs/3296716113/jobs/5436697247

Error: Cannot handle unknown node `inlineMath`

Have no idea which file(maybe this https://github.com/wenerme/wener/blob/master/notes/algorithm/ml/cs221-reflex.md), which line cause the error.

EDIT

cause is founded but the problem is missing file context

@shermanhui as mentioned above, if you want to contribute you can directly open a PR. If I have to spend time explaining things to you, it will be faster for me to solve the bug myself. Error Cause is a standard EcmaScript feature, you will find everything on Google or in the spec

@shanpriyan opened a PR already so it is too late now for this issue, but you can open a PR to another one if you want
