I am facing issue in Question set when i click on ADD FROM LIBRARY the bellow one is the request to get objectType:["Question"].
but i am getting count 0 only.

=> i have created object category of Multiple choice Question and objectType as Question.

curl --location --request POST 'https://uphrh.in/api/composite/v1/search'
--header 'Content-Type: application/json'
--header 'Authorization: Bearer '
--data-raw '{
"request": {
"query": "",
"filters": {
"primaryCategory": [
"Multiple Choice Question"
],
"status": [
"Live"
],
"objectType": [
"Question"
]
},
"sort_by": {
"lastUpdatedOn": "desc"
}
}
}'

@pallakartheekreddy - can you check and respond please?

@BharathTarento I guess you created MCQ Question under Question Set right? If yes, those questions will not appear in search as those questions created with Visibility as Parent means those questions will be to exist only under that Question Set.

thank you @pallakartheekreddy it worked for me.
Could you please elaborate more for Visibility Private and Protected Functionalities in the system.

@maheshkumargangula - can you clarify if 'private' & 'protected' are implemented in Knowlg BB?
