SyntaxError: Invalid regular expression: invalid group specifier name

See original GitHub issue

Hey, I’m getting this error here on iOS and macOS Safari:

SyntaxError: Invalid regular expression: invalid group specifier name

It comes from here:

// Remove duplicate slashes if not preceded by a protocol
if (urlObj.pathname) {
  urlObj.pathname = urlObj.pathname.replace(/(?<!https?:)\/{2,}/g, '/');
}

My code: https://github.com/muuvmuuv/portfolio/blob/master/src/elements/Link.jsx Live error: https://portfolio-git-development.muuvmuuv.now.sh/

I am using version 5.x

Hey, I’m coming from Gatsby, thanks a lot for this issue. As mentioned above, it’s a critical issue.

And this has been open for a while. Any Idea why there hasn’t been any progress on something that seems like a simple syntax error?

Thanks
