Expression rule error if input does not exist.

Hi,

can share the code?

Here is the rule I used:

with(
a!queryEntity(
entity: cons!TEMS_ENTITY_V_TE_DETAILS,
query: a!query(
paginginfo: if(rule!APN_isBlank(ri!pagingInfo) , a!pagingInfo(1, - 1,a!sortInfo(field: "etemId",ascending: true)),ri!pagingInfo),
logicalexpression: a!queryLogicalExpression(
ignorefilterswithemptyvalues: true,
operator: "AND",
filters: {
a!queryFilter(
field: "id",
operator: "includes",
value: ri!id
),
a!queryFilter(
field: "etemId",
operator: "=",
value: ri!etemId
),

a!queryFilter(
field: "eterfId",
operator: "=",
value: ri!eterfId
),
a!queryFilter(
field: "cafNumber",
operator: "includes",
value: ri!cafNumber
),
a!queryFilter(
field: "uniqueId",
operator: "=",
value: ri!uniqueId
),
a!queryFilter(
field: "appianDocumentId",
operator: "=",
value: ri!appianDocumentId
),
a!queryFilter(
field: "caseId",
operator: "=",
value: ri!caseId
),
a!queryFilter(
field: "excursionId",
operator: "=",
value: ri!excursionId
),
a!queryFilter(
field: "excursionRangesId",
operator: "=",
value: ri!excursionRangesId
),
a!queryFilter(
field: "justification",
operator: "includes",
value: ri!justification
),
a!queryFilter(
field: "minObservedTempOfTe",
operator: "=",
value: ri!minObservedTempOfTe
),
a!queryFilter(
field: "maxObservedTempOfTe",
operator: "=",
value: ri!maxObservedTempOfTe
),
a!queryFilter(
field: "maxTotalDurationOfTe",
operator: "includes",
value: ri!tlDurationOfTe
),
a!queryFilter(
field: "dispositionStatus",
operator: "=",
value: ri!dispositionStatus
),
a!queryFilter(
field: "createdBy",
operator: "includes",
value: ri!createdBy
),
a!queryFilter(
field: "approvedByName",
operator: "includes",
value: ri!approvedByName
),
a!queryFilter(
field: "approvedByDate",
operator: "=",
value: ri!approvedByDate
),
a!queryFilter(
field: "approverRole",
operator: "includes",
value: ri!approverRole
),
a!queryFilter(
field: "emailSent",
operator: "includes",
value: ri!emailSent
),

a!queryFilter(
field: "capa",
operator: "=",
value: ri!capa
),
a!queryFilter(
field: "comments",
operator: "includes",
value: ri!comments
),

a!queryFilter(
field: "permittedTeRange",
operator: "includes",
value: ri!permittedTeRange
),
a!queryFilter(
field: "calculatedTime",
operator: "includes",
value: ri!calculatedTime
),
a!queryFilter(
field: "disposition",
operator: "includes",
value: ri!disposition
),
a!queryFilter(
field: "justification",
operator: "includes",
value: ri!justification
),

a!queryFilter(
field: "timeAllowableForFutureExcursion",
operator: "=",
value: ri!timeAllowableForFuture
)
}
),

),
fetchTotalCount: true
)
)

Next time please use

Would you please post the actual error message.

And please explain what "error in expression rule when rule input does not exist in the entity parameter" means. In your code, the entity is a constant. Why can that be empty?

This is the error I get when there is no budget id exists corresponding to etem id passed as rule input:

Expression evaluation error at function rule!APN_distinct [line 2]: Invalid index: Cannot index property 'budgetId' of type String into type List of Variant

Code:

rule!APN_distinct(with(
a!queryEntity(
entity: cons!TEMS_ENTITY_LINK_HEADER_BUDGET,
query: a!query(
paginginfo: a!pagingInfo(1,-1),
logicalexpression: a!queryLogicalExpression(
operator: "AND",
filters: {
if(isnull(ri!etemId),
{},
a!queryFilter(
field: "etemId",
operator: "=",
value: ri!etemId
)
),
/*a!queryFilter(
field: "eterfId",
operator: "not in",
value: {""}
), */
if(isnull(ri!budgetId),
{},
a!queryFilter(
field: "budgetId",
operator: "=",
value: ri!budgetId
)
)
}
)
),
fetchTotalCount: true
).data.budgetId
) )

Please use

If the query does not return any values, the dot-notation "data.budgetId" breaks. Using index() would help here.

What is the with() doing?
