【bug】连续对一张图片进行 variation 操作，第二次获取结果会与第一次的结果相同

[allentofight]

重现如下

1. 首先请求 promt 调用 imagine
curl -X POST http://mywebsite.com/api/v1/trigger/submit \
-H "Content-Type: application/x-www-form-urlencoded" \
-d "action=IMAGINE&prompt=I'm%20a%20basketball%20player"

返回结果 {"code":1,"description":"成功","result":"b9b52d08-19fe-4b8b-a608-3ffdaa079d83"}

2. 对 result 进行查询
{"_id":"b9b52d08-19fe-4b8b-a608-3ffdaa079d83","index":"","action":"IMAGINE","prompt":"I'm a basketball player","promptEn":"I'm a basketball player","taskId":"1114932607285739642","uri":"https://cdn.discordapp.com/attachments/1112940597846749228/1114932607596114012/qiuweiai_Im_a_basketball_player_7061e2e2-005c-4d28-9b54-6d8d55fe357f.png","hash":"7061e2e2-005c-4d28-9b54-6d8d55fe357f","content":"I'm a basketball player --seed 7563 --v 5","progress":"done","description":"/imagine I'm a basketball player","submitTime":1685890985401,"finishTime":1685891050723,"creationTime":1685890984883,"state":"","notifyHook":"","imageUrl":"https://cdn.discordapp.com/attachments/1112940597846749228/1114932607596114012/qiuweiai_Im_a_basketball_player_7061e2e2-005c-4d28-9b54-6d8d55fe357f.png","status":"SUCCESS"}


3. 对以上图片第一张进行 variation

curl -X POST http://mywebsite.com/api/v1/trigger/submit \
-H "Content-Type: application/x-www-form-urlencoded" \
-d "action=VARIATION&taskId=b9b52d08-19fe-4b8b-a608-3ffdaa079d83&index=1"

返回结果 {"code":1,"description":"成功","result":"4b880546-dd90-4b65-9a66-49ffdd825a1e"},查询后返回
{"_id":"4b880546-dd90-4b65-9a66-49ffdd825a1e","index":"1","action":"VARIATION","taskId":"1114934375323287572","uri":"https://cdn.discordapp.com/attachments/1112940597846749228/1114934375713362001/qiuweiai_Im_a_basketball_player_c2054672-a8f4-45c3-a137-501dc6d63c32.png","hash":"c2054672-a8f4-45c3-a137-501dc6d63c32","content":"I'm a basketball player --seed 7563 --v 5","progress":"done","description":"/imagine undefined","submitTime":1685891431750,"finishTime":1685891471130,"creationTime":1685891430160,"state":"","notifyHook":"","imageUrl":"https://cdn.discordapp.com/attachments/1112940597846749228/1114934375713362001/qiuweiai_Im_a_basketball_player_c2054672-a8f4-45c3-a137-501dc6d63c32.png","status":"SUCCESS"}
这一次结果正常


4. 对步骤 2 的图片第二张进行 variation
curl -X POST http://mywebsite.com/api/v1/trigger/submit \
-H "Content-Type: application/x-www-form-urlencoded" \
-d "action=VARIATION&taskId=b9b52d08-19fe-4b8b-a608-3ffdaa079d83&index=2"
最终的返回结果和步骤3一样!
