Problem in query entuty

Question

Hi,

I am facing very weird issue when I am using the query entity the issue is like that
"Expression evaluation error at function a!queryEntity: An error occurred while retrieving the data."

For that, I am using View for retrieve the data from db

I am using query entity like that.,but I am getting the above problem..
a!queryEntity(
entity: cons!BPMF_V_BPMF_TASK_DETL,
query: a!query(
selection: a!querySelection(
columns: {
a!queryColumn(
field : "REQ_TYPE_NME"
)
}
),
pagingInfo : a!pagingInfo(
startIndex: 1,
batchSize : 1
)
))

But I am creating query rule for the same entity(View)..it is working fine
I am not sure where i am doing wrong please help.

This error message is usually either that view has a performance issue and that query is timing out on the Appian side or the structure of the of the view has been changed and the XSD from the cdt doesn't match. Please verify those 2 things and that should resolve your problem.
