The parameters of waline does not take effect.

[L-Super]

1. I am using waline, I found that some issues exist as the requiredMeta and placeholder parameters do not seem to take effect.

2. Are the parameters correct?
   hugo-theme-stack-starter/config/_default/params.toml:

requiredMeta = ["name", "email", "url"]

CaiJimmy/hugo-theme-stack#811:

requiredMeta:
                - nick
                - mail

3. At the same time, there is no documentation explaining the meaning of the parameters.
