Retrieving huge amount of data

Hi,

I have created a view to display it in read only grid. 

There is huge amount of data that needs to be retrieved and displayed.

But when am writing simple query to fetch data am getting error:

a!queryEntity(
entity: cons!AB_DE_V_DD,
query: a!query(

pagingInfo: if(
rule!APN_isEmpty(
ri!pagingInfo
),
a!pagingInfo(
startIndex: 1,
batchSize: 50
),
ri!pagingInfo
)
)
)

Error: Expression evaluation error at function a!queryEntity: An error occurred while retrieving the data.

Can someone help to sort this issue.

Note: When am using filter to retrieve data, am not getting any error
