Invalid Multi-match

Why This Error Occurred

In one of your custom-routes you specified a multi-match /:path* and used it in your destination without adding the * in your destination e.g. destination: '/another/:path'

Possible Ways to Fix It

Add * to your usage of the multi-match param in your destination.

Before

{
  source: '/:path*',
  destination: '/another/:path'
}

After

{
  source: '/:path*',
  destination: '/another/:path*'
}
