[BUG] Valid PUUID from LEAGUE-EXP-V4 is returning 404 in ACCOUNT-V1

[victorhaynes]

Bug Description
A PUUID returned from https://kr.api.riotgames.com/lol/league-exp/v4/entries/RANKED_FLEX_SR/MASTER/I?page=1 does not exist when you search that same PUUID in https://asia.api.riotgames.com/riot/account/v1/accounts/by-puuid/oliCy91SaeSj0s5NYxSAjJ7MuqrTsgE3QoY5dR2fofc7D8RxOXMjhblgLvznC8XNFMijo3jgrrVllg
I confirmed this behavior with other developers.

The ACCOUNT-V1 response is

https://asia.api.riotgames.com/riot/account/v1/accounts/by-puuid/oliCy91SaeSj0s5NYxSAjJ7MuqrTsgE3QoY5dR2fofc7D8RxOXMjhblgLvznC8XNFMijo3jgrrVllg

{
    "status": {
        "status_code": 404,
        "message": "Data not found - Not Found"
    }
}

Expected Result
Expect a response with status code 200 along with gamename/tagline etc

Actual Result
404

Developer Impact
Cannot build an accurate leaderboard for an entire region & cannot create basic profile pages for certain players.

• Frequency: Every API call
• Severity: High. Some players cannot use my application (or anyone else's) to view their own details or an accurate leaderboard. Basic application logic assumes that all PUUIDs coming from Riot responses are valid.
• Cost: N/A cannot be worked around.
• Efficiency: N/A cannot be worked around.

Player Impact
Cannot build an accurate leaderboard for an entire region & cannot create basic profile pages for certain players.

• Frequency: Every time the user visits the site, they experience this issue.
• Severity: Certain users cannot use my site for themselves and no users can view accurate leaderboards
• Region: I have only ever experienced in KR

Preconditions
N/A

First condition
N/A

Repro Steps

1. Send a GET request to https://kr.api.riotgames.com/lol/league-exp/v4/entries/RANKED_FLEX_SR/MASTER/I?page=1
2. Try to identify this player puuid: oliCy91SaeSj0s5NYxSAjJ7MuqrTsgE3QoY5dR2fofc7D8RxOXMjhblgLvznC8XNFMijo3jgrrVllg. Note that the ladder changes so they may move over time. If a Rioter has the ability to identify a player based on my encrypted PUUID/SummonerId please try to do that.
3. Take the player's PUUID and look them up in ACCOUNT-V1 https://asia.api.riotgames.com/riot/account/v1/accounts/by-puuid/oliCy91SaeSj0s5NYxSAjJ7MuqrTsgE3QoY5dR2fofc7D8RxOXMjhblgLvznC8XNFMijo3jgrrVllg

Issue Comments
Note that the ladder changes so the player's/PUUID's position may move in the ladder. If a Rioter has the ability to identify a player based on my encrypted PUUID/SummonerId please try to do that.
