Just faced this error a day ago in my code.
Try to check the rows you're trying to retrieve. There are one or multiple null values in the DB which shouldn't be null.
Once you add some dummy values to them (to verify this is the issue), it should work fine.

1 Download ddl check all the query is

working fine or not

2- create new test expression rule and only pass query and paging info do not do any calculations if you get same errors then problem would be in data base side or the constant which holding the entity

3 - check the datatype whether the entity is added on the Data store or not

Hi, There are multiple things you can do enhance your performance,

1. Try to use selection in your query, query only necessary columns

2.avoid using wildcase ("like","in") operators in filters

3.use proper batch size

4.check query execution time in database and see explain plan tab for explanation to see where delay is happening

One more thing, did you try to use queryrecordtype? I have seen querying record type is little faster than query entity.

use paging info.When you retrieve the query you can limit the data.

paginginfo: a!pagingInfo(
startIndex: 1,
batchsize:100
)

If you are providing batch size is -1 means it will retrieve all the data from the table.Use Filter option to filter the data as per your requirement.

Yes, it’s pulling large data. Any suggestion to resolve this issue

Hi,

There are a few possible causes for this issue:

There is a lock on the database.
There is too much data being pulled back.
The query timed out.
