Description

I was able to reproduce this both in a live installation (Version: Apache kylin 3.0.1, Commit: 638a1eb68f257366d240105b33e5eea3bfa4dbf3) as well as by running the apachekylin/apache-kylin-standalone:4.0.0 docker container (Version: Apache kylin 4.0.0, Commit: aa6d582c0a96fdf31e85791f86850cfc00a7644f).

Steps to Reproduce

1) Pull image

docker pull apachekylin/apache-kylin-standalone:4.0.0

2) Run apache-kylin-standalone

docker run -d -m 8G -p 7070:7070 -p 8088:8088 -p 8032:8032 -p 8042:8042 -p 2181:2181 apachekylin/apache-kylin-standalone:4.0.0

3) Authenticate

curl --location --request POST 'http://127.0.0.1:7070/kylin/api/user/authentication' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic QURNSU46S1lMSU4=' \
-c cookiefile.txt

3a) Expected response:

{"userDetails":{"username":"ADMIN","password":"$2a$10$o3ktIWsGYxXNuUWQiYlZXOW5hWcqyNAFQsSSCSEWoC/BRVMAUjL32","authorities":[{"authority":"ROLE_ADMIN"},{"authority":"ROLE_ANALYST"},{"authority":"ROLE_MODELER"},{"authority":"ALL_USERS"}],"disabled":false,"defaultPassword":false,"locked":false,"lockedTime":0,"wrongTime":0,"uuid":"d40b9088-f450-0966-cccb-a3c5ccf6a46e","last_modified":1632157513006,"version":"4.0.0.0"}}

4) Try to refresh kylin_sales_cube, but omit the buildType from the payload:

curl --location --request PUT 'http://127.0.0.1:7070/kylin/api/cubes/kylin_sales_cube/build' \
--header 'Content-Type: application/json' \
--data-raw '{  
   "startTime": "1546300800000",
   "endTime": "1609459200000"
}' \
-b cookiefile.txt

Error response:
