[BUG] missing matchlists

[jadeeeeh]

Bug Description
When I search for a player's matchlists within a specific time range by using /lol/match/v5/matches/by-puuid/{puuid}/ids, it always responds with an empty list, even when this player have played games within the time range.

Problem Description
I tried to find a player's matchlists from 1637078400000 to 1637596800000 by his puuid. This is the request url. https://americas.api.riotgames.com/lol/match/v5/matches/by-puuid/dRi8Sin5w45gjBobLQ108kqM1xMvgYSZxdTe3e3m8p-Uhn5h49bm6v9A63YP7BLNL3mavk_rI7NYQw/ids?startTime=1637078400000&endTime=1637596800000&start=0

The response code is 200, but response body is empty. ([])

However, when I check the player's gaming history without setting time range, I can find at least one match within that time range. When I using https://americas.api.riotgames.com/lol/match/v5/matches/by-puuid/dRi8Sin5w45gjBobLQ108kqM1xMvgYSZxdTe3e3m8p-Uhn5h49bm6v9A63YP7BLNL3mavk_rI7NYQw/ids?start=0 I can get [ "NA1_4107800373", "NA1_4107698532", "NA1_4107117377", "NA1_4106370540", "NA1_4104754740", "NA1_4104712450", "NA1_4101727248", "NA1_4101739993", "NA1_4101619711", "NA1_4100295348", "NA1_4100036372", "NA1_4099523439", "NA1_4099259022", "NA1_4098696333", "NA1_4098217136", "NA1_4098060508", "NA1_4097148170", "NA1_4097193623", "NA1_4097078861", "NA1_4097048095" ]

The first game in the list ("NA1_4107800373") occurred at TimeStamp 1637221824000, which is within the time range I set at the beginning (1637078400000- 1637596800000). I tried to delete the endtime using the first url but still get the same result.

Expected Result
My expected result should be the matchlists finished by the player within specific time range.

Actual Result
I got an empty list with response code 200. But this player did play the game during that time period.

Developer Impact
This issue is very severe for me as I would like to collect the gaming history for a player within the whole season. I cannot continue my project with this problem.

• Frequency: Every API call. Once every ~100 API calls.
• Severity: When it happens, my project cannot continue.
• Cost: My dissertation cannot finish.

Preconditions
This bug happens when developers searching for matchlists within a specific time range.

Hi jadeeeeh,

This is intentional. If you read the startTime parameter on the developer portal it reads the following:

Epoch timestamp in seconds.

The examples you gave are timestamps in milliseconds, which means you are searching for a range way in the future so you are receiving no games.

Closing out old issues. This doesn't appear to be an API issue, if you feel this is in error, please re-open/comment.
