netlify-plugin-sitemap: Sitemap Not Available

I had an issue with my Sitemap with the recent update. It used to work before with my configuration in my netlify.toml.

When I tried to visit my sitemap, I would end up with a 404 page. Previously, I did not define the buildDir in the past because the default value worked for me. After reading issue #33, I set my buildDir to "./" and that loads my sitemap. However, it’s blank.

I changed it to buildDir = "publish" like the documentation, but I get the 404 again.

Here’s my config:

# Sitemap
[[plugins]]
package = "@netlify/plugin-sitemap"

[plugins.inputs]
buildDir = "publish"
prettyURLs = true
trailingSlash = true
exclude = [
    "**/404.html"
]

Please let me know the default buildDir to use. I have my repo hosted on GitHub, but it’s private.
