This won’t work as acct-input-octets-ipv6 is not a standard RADIUS attribute. It is text as the value of a Cisco-AVPair attribute.
You will need to define this attribute if you want to be able to use it in your FreeRADIUS config.

Your regex is not correct. You are not escaping the trailing ), which I presume you need to do. You can test this regex with standard regex tools - you should make sure your regex is correct and matches examples you feed it. There are a bunch of “online” regex testers, if you don’t have other ways of doing this.

I don’t think you should have brackets around the acct-input-octets-ipv6 either - you are not extracting this text. You should only have brackets around the part you wish to capture (i.e. the \d), and then use %{1} not %{2}.
