i'm new to Appian. I have an issue with expression rule. my rule is as follows:

a!queryEntity(
entity: cons!LCW_BUSINESS_UNIT_ENTITY,
query: a!query(
filter: if(
rule!APN_isEmpty(ri!businessDivision.id),
{},
a!queryFilter(
field: "businessDivision.id",
operator: "=",
value: ri!businessDivision.id)
),
pagingInfo: a!pagingInfo(
startIndex: 1,
batchSize: -1,
sort: a!sortInfo(
field: "order",
ascending: true
)
)
),
fetchTotalCount: true
)

but when i execute this i get the following error

Expression evaluation error at function a!queryEntity: Cannot apply a filter with a blank field name.

can you pls help?

@karthikeyan in the attached code under querylogicalExpression and in under filters part you have written the logicalExpression part inside which is not acceptable as per syntax. I have removed that code under filters part and placed it under logicalexpression part and attaching the snippets for comparsion.

And what sikhi said is correct actually, we don't need it but we had the same issue in one case. So suggested to do the same. Hope it will help.

@karthikeyans75 - There is a small syntactical error. In the a!queryLogicalExpression, you have "filters" and inside that you have included "logicalExpressions" which is not correct. Both should be separate. Please refer the updated code snippet.

Please refer the link below link for more information.

Hope the information is helpful.

@Karthikeyan Hi,
I have updated your code slightly and attached, Try with this code and let me know if there are any issues,

@sikhivahans, thanks for the refactoring. The new code gives the same error too

@mohanp, I added naics col too, it didnt work. The same query works fine when I take off the nested condition

@pavang If you meant to say that a column should be queried in order to apply filter on it, just to let you know, to the best of my knowledge, that's not correct. You can still apply the filter on a column though it's not retrieved. (Reference: https://forum.appian.com/suite/help/16.1/Query_Recipes.html#Retrieve_the_Data_for_a_Single_Field. The 'id' column isn't being retrieved, yet it's used as filter.)

In short, there isn't a need to retrieve 'naics' just because of the reason that a filter is applied on it.

@mohanp In addition to the above comments in the attached snippet code, you are applying the filter based on one column named "naics", but you are not querying the that column. Try to query that required one and check it. Hope it will work.

@karthikeyans Hi, I have refactored your code slightly(as per my knowledge, I felt the need of doing so) and it would be worth testing the attached code snippet and letting us know if there are any issues still.

Ahh Thanks Sikhivahan. I missed that.

sikhivahans — Mon, 16 May 2016 11:43:13 GMT

@mohanp If you are talking about the 'id' filter in the code snippet, just to let you know, the 'value' parameter is optional when 'not null' is applied as filter(Reference: https://forum.appian.com/suite/help/16.1/Appian_Data_Types.html#QueryFilter). So that may not be a issue at all.

Notice line no 32, it seems you missed to pass value parameter to queryFilter.
