TCL error for basic ACL iRule

Does someone know why this TCL error is happening? I'm running 11.4.1 HF2

Apr 13 11:28:49 F5-AS400-LB-ACTIVE err tmm3[12193]: 01220001:3: TCL error: /Common/source_filter  - bad action "172.17.1.250": must be match, search, lookup, element, type, exists, size, names, get, startsearch, nextelement, anymore, or donesearch     while executing "class [IP::client_addr] equals allowed_datagroup"

    when RULE_INIT {
     v1.0 - basic ACL.
     January, 2014
    
     Purpose: 
       Bind this rule to a virtual server to simply allow or disallow traffic based on source IP. 
       This rule expects a datagroup that lists the addresses you wish to allow. 
       By default, traffic will be dropped.
    }
    when CLIENT_ACCEPTED  {

            if { [class [IP::client_addr] equals allowed_datagroup] }{

                    Uncomment the line below to turn on logging.
                    log local0.  "Valid client IP: [IP::client_addr] - forwarding traffic"
                    forward
            } else {

                    Uncomment the line below to turn on logging.
                    log local0. "Invalid client IP: [IP::client_addr] - discarding"
                    discard
            }

    Here is the datagroup: ltm data-group internal /Common/allowed_datagroup { records { 10.12.20.0/22 { } 10.12.25.0/24 { } 10.12.28.0/24 { } 172.18.50.0/24 { } } type ip }

    This was the fix. I removed 'forward' too. 

    when RULE_INIT {
     v1.0 - basic ACL.
     January, 2014
    
     Purpose: 
       Bind this rule to a virtual server to simply allow or disallow traffic based on source IP. 
       This rule expects a datagroup that lists the addresses you wish to allow. 
       By default, traffic will be dropped.
    }
    when CLIENT_ACCEPTED  {

            if { [class match [IP::client_addr] equals allowed_datagroup] }{

                    Uncomment the line below to turn on logging.
                    log local0.  "Valid client IP: [IP::client_addr] - forwarding traffic"
            } else {

                    Uncomment the line below to turn on logging.
                    log local0. "Invalid client IP: [IP::client_addr] - discarding"
                    discard
            }

    }

    Can simplify it a bit:

    when RULE_INIT {
     v1.0 - basic ACL.
     January, 2014
    
     Purpose: 
       Bind this rule to a virtual server to simply allow or disallow traffic based on source IP. 
       This rule expects a datagroup that lists the addresses you wish to allow. 
       By default, traffic will be dropped.
    }
    when CLIENT_ACCEPTED  {
            if { ! [class match [IP::client_addr] equals allowed_datagroup] }{
                    log local0. "Invalid client IP: [IP::client_addr] - discarding"
                    discard
            }
    }
