This is the block it has issues with:

resource "iosxe_restconf" "nested_list" {
  path = "Cisco-IOS-XE-wireless-wlan-cfg:wlan-cfg-data/wlan-cfg-entries"
  lists = [{
    name = "wlan-cfg-entry"
    key  = "profile-name"
    items = [
      for idx, ssid in var.cfg.ssids : {
        "profile-name"                  = try(ssid.profile, ssid.name)
        "wlan-id"                       = ssid.number  # Auto-increment WLAN ID starting from 1
        "auth-key-mgmt-psk"             = try(ssid.auth_psk, true)    # Default to true if not specified
        "auth-key-mgmt-dot1x"           = try(ssid.auth_dot1x, false) # Default to false if not specified
        "psk"                           = ssid.psk
        "apf-vap-id-data/ssid"          = ssid.name
        "apf-vap-id-data/wlan-status"   = try(ssid.status, true) # Default to true if not specified
      }
    ]
  }]
}

This cropped up between 0.5.6 and 0.5.9. Is it my code or an issue in the provider?

Thanks,

Steven.
