  ]
}

I originally suspected it might be an escape sequence issue or an string length issue, and indeed, description field is the culprit here. However, this issue is only reproduced when trying to paste the above string as a whole. Neither of the following (description only OR everything except description) does not reproduce the issue.

"description": "{\"name\":\"Qingping Air Monitor Lite\",\"device_id\":\"31:1e:54:5a:24:54\",\"model\":\"CGDN1\",\"category\":\"10\",\"transport\":\"ip\",\"paired\":true,\"pairable\":false,\"status_flags\":0,\"config_num\":1,\"state_num\":8,\"address\":\"192.168.0.39\",\"addresses\":[\"192.168.0.39\"],\"port\":80,\"protocol_version\":\"1.1\",\"setup_hash\":null}",

{
  "manager_id": "tc2_apple-homekit",
  "action": "scan",
  "things": [
    {
      "id": "tc2_homekit_setup_31_1e_54_5a_24_54",
      "location": null,
      "manager_id": "tc2_apple-homekit",
      "nick_name": "Qingping Air Monitor Lite",
      "skills": [],
      "functions": [],
      "values": [],
      "predefined_tags": [
        "tc2_homekit_setup_31_1e_54_5a_24_54",
        "tc2_apple-homekit"
      ],
      "tags": [
        "AppleHomeKit",
        "platform__AppleHomeKit",
        "HomeKitSetup",
        "CGDN1",
        "ip"
      ],
      "state": "scanned",
      "url": "homekit://31:1e:54:5a:24:54",
      "primary_skill": null
    }
  ]
}

What steps can reproduce the bug?

1. Open Codex extension
2. Paste the following string

{
  "manager_id": "tc2_apple-homekit",
  "action": "scan",
  "things": [
    {
      "id": "tc2_homekit_setup_31_1e_54_5a_24_54",
      "description": "{\"name\":\"Qingping Air Monitor Lite\",\"device_id\":\"31:1e:54:5a:24:54\",\"model\":\"CGDN1\",\"category\":\"10\",\"transport\":\"ip\",\"paired\":true,\"pairable\":false,\"status_flags\":0,\"config_num\":1,\"state_num\":8,\"address\":\"192.168.0.39\",\"addresses\":[\"192.168.0.39\"],\"port\":80,\"protocol_version\":\"1.1\",\"setup_hash\":null}",
      "location": null,
      "manager_id": "tc2_apple-homekit",
      "nick_name": "Qingping Air Monitor Lite",
      "skills": [],
      "functions": [],
      "values": [],
      "predefined_tags": [
        "tc2_homekit_setup_31_1e_54_5a_24_54",
        "tc2_apple-homekit"
      ],
      "tags": [
        "AppleHomeKit",
        "platform__AppleHomeKit",
        "HomeKitSetup",
        "CGDN1",
        "ip"
      ],
      "state": "scanned",
      "url": "homekit://31:1e:54:5a:24:54",
      "primary_skill": null
    }
  ]
}

1. Codex VS Code extension crashes

What is the expected behavior?

Pasting the string should populate the string in the text field instead of crashing the whole extension, obviously.
