Azure scim provsioing is not sending user role details in scim post request body

Question

source attribute: SingleAppRoleAssignment([appRoleAssignments])

I am using roles[primary eq true].value as mapping. With this role details is not present in post request. Getting role details in patch request only. can anyone help with this ?

I also tried roles[primary eq "True"].value and got role value in patch request. Azure sends primary: true in post req. But in patch req getting roles[primary eq "True"] (boolean strings). Why sending boolean in post and string in patch ?

I tried this with both provision on demand and normal job behaviour.
