Having the same issue for the first time. Tried to:

Seems like initially it scrapes the first page and getting the error once needed to scroll.

Released an update for the desktop app, I'll deal with the browser-only version later.

The issue is because of the querySelector using nav header h1[class*='name-'], as it's considered null. Rewriting it to check if it's in a guild, and iterating through the children of nav header [class*='headerContent-'] fixes this.

for (const child of r(document.querySelector("nav header [class*='headerContent-']")).children) {
    if (child && child.props && child.props.guild) {
        guild = child.props.guild;
        break
    }
}

I will update the browser-only version tomorrow. Fixing code is the easy part, it's the testing + build + deployment + wiki that are the most tedious and time-consuming parts of updating the browser-only version (and honestly, automating the process is not really worth it, since the browser-only version is only getting occasional critical fixes).
