parentTeamId of player sometimes missing in statsapi.boxscore_data(game_id)

[tobiask84]

To reproduce for example store this game into a json:

import json
import statsapi

# Get game data for specific game ID
game_id = "778110"

try:
    # Get game data
    game_data = statsapi.boxscore_data(game_id)
    
    # Write game data to file
    output_file = f"{game_id}.json"
    with open(output_file, "w") as f:
        json.dump(game_data, f, indent=2)

Now check the player Blubaugh:

    "ID805123": {
        "person": {
          "id": 805123,
          "fullName": "AJ Blubaugh"

parentTeamId is missing. All other players in this file have the parentTeamId within the player. Why not Blubauh :) ?

I understand that all players are either under "home" or "away". So I can retrieve the info from there. I'm still wondering why all players except Blubauh in this response have the id within the player json? Is there a reason the info is not present for this specific player?

I suspect it is because this is the only game he was on the active roster, he was optioned back to their Triple-A team the next day.

If you look at a player who has since been traded, I wonder what their parent team ID would be for a game on their previous team.
