Service_L4 persistenceMethods blank none error

[JeffGiroux]

I'm trying to have a runtime init yaml install and declare AS3 with a Service_L4 service. I want persistence None, but the default for Service_L4 is sourceIP. No matter what combination I try, runtime init keeps failing.

From reading the docs on AS3, you can supply an empty array with empty brackets [], but I tried and it failed.

BIG-IP version = 15.1.0.2
Runtime init = 1.3.2

Expected Behavior

I want to deploy a Service_L4 with persistence none in runtime init with this type of AS3 json. Notice a blank array for persistence methods.

{
    "class": "ADC",
    "schemaVersion": "3.0.0",
    "tenant": {
        "class": "Tenant",
        "application": {
            "class": "Application",
            "service": {
                "class": "Service_L4",
                "virtualPort": 1701,
                "virtualAddresses": [
                    "0.0.0.0/0"
                ],
                "persistenceMethods": []
            }
        }
    }
}

Actual Behavior

Tried various ways to set persistence none in runtime init as3 yaml, but error.

              forwarder_tcp_ipv4_1701-to-25:
                class: Service_L4
                remark: Forwarding port 1701-to-25 IPv4
                allowVlans:
                  - internal
                virtualAddresses:
                  - '0.0.0.0/0'
                virtualPort: 1701
                layer4: tcp
                profileL4: basic
                snat: auto
                persistenceMethods: []
                translateServerAddress: false
                translateServerPort: true

1. tried with empty brackets

persistenceMethods: []
zzznextthingzzz:

error = error: {"code":422,"errors":["/Tenant1/App1/forwarder_tcp_ipv4_1701-to-25/persistenceMethods: should be array"],"declarationFullId":"","message":"declaration is invalid"}

2. tried with 'none'

persistenceMethods:
 - none
zzznextthingzzz:

error = error: {"code":422,"errors":["/Tenant1/App1/forwarder_tcp_ipv4_1701-to-25/persistenceMethods/0: should be equal to one of the allowed values ["cookie","destination-address","msrdp","source-address","tls-session-id"]"],"declarationFullId":"","message":"declaration is invalid"}

3. tried leaving blank

persistenceMethods:
zzznextthingzzz:

error = error: {"code":422,"errors":["/Tenant1/App1/forwarder_tcp_ipv4_1701-to-25/persistenceMethods: should be array"],"declarationFullId":"","message":"declaration is invalid"}

4. tried with blank array

persistenceMethods:
 -
zzznextthingzzz:

error = error: {"code":422,"errors":["/Tenant1/App1/forwarder_tcp_ipv4_1701-to-25/persistenceMethods: should be array"],"declarationFullId":"","message":"declaration is invalid"}

Workaround

I use Service_Generic which has a default persistence of none. That way, I do not have to set 'none' which apparently cannot be set properly right now. Hence, new ticket :)

[JeffGiroux]

Currently have my service_generic workaround in my runtime init yaml within this onboard file if you need to reference anything.

Thanks for the detailed writeup. Something is definitely not working right here. We are now tracking this bug internally with ID ESECLDTPLT-2890.

@JeffGiroux Hi Jeff, I just attempted to repro this, but was unable to. I was using runtime init v1.4.0 and AS3 3.33.0.

Worked both with a HTTP and L4 service. Would you mind retrying with those versions?
thanks
