iosxe_restconf does not seem to support empty json

[mobig]

when you enable static route redistribution on an IOSXE device, the REST ends up looking like so:

{
    "Cisco-IOS-XE-bgp:bgp": [
        {
            "id": 65000,
            "bgp": {
                "log-neighbor-changes": true
            },
            "neighbor": [
                {
                    "id": "192.168.0.153",
                    "remote-as": 65000,
                    "description": "BGP Neighbor 1"
                }
            ],
            "address-family": {
                "no-vrf": {
                    "ipv4": [
                        {
                            "af-name": "unicast",
                            "ipv4-unicast": {
                                "neighbor": [
                                    {
                                        "id": "192.168.0.153",
                                        "activate": [
                                            null
                                        ],
                                        "route-map": [
                                            {
                                                "inout": "in",
                                                "route-map-name": "RM1"
                                            }
                                        ],
                                        "route-reflector-client": [
                                            null
                                        ]
                                    }
                                ],
                                "redistribute": {
                                    "static": {}
                                }
                            }
                        }
                    ]
                }
            }
        }
    ]
}

the issue is i have not found a way to pass an empty json "{}" using iosxe_restconf resource (which is what the routers seems to expect). this is what i'm trying

# BGP static redistribution
resource "iosxe_restconf" "bgp_redistribution" {
  for_each   = {for bgp in local.router_bgp : bgp.key => bgp}
  device     = each.key
  path       = "Cisco-IOS-XE-native:native/router/Cisco-IOS-XE-bgp:bgp=${each.value.asn}/address-family/no-vrf/ipv4=unicast/ipv4-unicast/redistribute/static"
  attributes = {
    "Cisco-IOS-XE-bgp:static" = "{}"
  }
}

when running this, i get the following error:

Stack trace from the terraform-provider-iosxe_v0.1.15.exe plugin:

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

any idea how this would be done?

[danischm]

Can you try this?

resource "iosxe_restconf" "bgp_redistribution" {
  for_each   = {for bgp in local.router_bgp : bgp.key => bgp}
  device     = each.key
  path       = "Cisco-IOS-XE-native:native/router/Cisco-IOS-XE-bgp:bgp=${each.value.asn}/address-family/no-vrf/ipv4=unicast/ipv4-unicast/redistribute"
  attributes = {
    "static" = ""
  }
}

with the HCL you provided, i'm still getting the error:

Is that maybe the same issue as in the other thread, where device is not a name but rather a URL?
