[BUG] Call for a player's match IDs using matchv5 not returning up-to-date matches

[NFeruch]

Bug Description
A call through matchv5's url of the form, "/lol/match/v5/matches/by-puuid/{puuid}/ids", returns old games only, and not that player's actual most recent games played

Problem Description
Getting a list of match IDs via a player's PUUID from matchv5 returns matches that were played over a week ago, and not their most recent ones.

Expected Result
I am expecting to get a list of a player's most recent matches played when calling matchv5's get match ids by puuid

Actual Result
matchv5 returns matches that are a week old from when the player has actually played. The player irl has played 1 day ago, but the API returns matches from 7+ days prior only

Developer Impact
I wish to implement an updating system, so that the player can review their most recent matches, but cannot because matchv5 is returning week-old matches only

• Frequency: Every API call
• Severity: Medium severity, blockade for further development
• Cost: Time that could be spent on advancement of features
• Efficiency: Cannot receive accurate data

Player Impact
If a player wishes to see their most recent matches, they are unable to via the api, which is frustrating

Preconditions
Calling the matchv5 url using a valid API key and valid puuid

Repro Steps
Step by step, what do you need to do to cause the bug? Note that GitHub will automagically number each step if you prefix the line with "1. "

1. A call to "https://americas.api.riotgames.com/lol/match/v5/matches/by-puuid/CYzJo3m60KnSlIoWnGAhVI7IpUBo2D4DC7hErpatH3FOiMUMjx-ZJXKVkYw-bzeqE_-e0r3QMDr_DA/ids?api_key=API_KEY_HERE&count=50", where "CYzJo3m60KnSlIoWnGAhVI7IpUBo2D4DC7hErpatH3FOiMUMjx-ZJXKVkYw-bzeqE_-e0r3QMDr_DA" is a sample player's puuid, return week old matches consistently. This should not be happening, because irl they have played within the last 7 days

Yep we're aware and working on restoring the matchlists.

[samuelbouliane]

Yes same here. The only return I get from this puuid: s2iDMaTZuTtL5oUix1gTXF0lvyB6g04lWlyne8i5zOYQyztMdlJdU6pOxus1wutvNl0S22M1LE4LPg is a game of Orianna somewhere around a week ago. Otherwise, most accounts seem to be up to date.

I had this problem a couple of days ago and now it seems to be fixed.

Still not entirely fixed. See ign "idunnololz" region "na". If you compare the last 20 games returned by match-v4 and match-v5 you can see some games are missing from match-v5

still doesn't fixed?

For the most part, we should be in a reasonably good state.

1. We've completed the match reconciliation in all riot regions, so players shouldn't be missing their match history.
2. The read replica the API uses is rarely behind (replication lag) and when it is it's not by much and quickly recovers.
3. We're seeing failed cache evictions where the player's matchlist isn't properly evicted from the cache when a new match is completed. We believe this is related to the reoccurring issues resulting in the service returning 503s. We're currently investigating this.

As such, we believe it should be relatively rare for a player's matchlist to be significantly behind (on the order of several matches). At most, we expect the majority of players to have their match list updated within minutes of them completing a match. A small number of players should be affected by the failed cache evictions mention in #3.
