We configured our CDN rules engine to serve a SPA application (which means redirecting any request to the index.html page if it's not an asset or a static file).
Our rule was working well but we needed to update some condition on it. Validating it gave us this error
Of course, putting /. in doesn't work as expected but / isn't a valid source anymore. Neither do regex like /.+ or /*
Any feedback would be helpful to get a valid SPA rule back to work.
Thank you
