Facing Error in Interface with local variables

Hi Team,

I have an interface which contains the below code:

a!localVariables(

For this code, I am getting the error:

Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error: Rule and function references cannot be stored in local variables. local!category contains one or more rule or function references.

AFAIK, we are allowed to save the values of rule in a local variable.

Below is the code for rule!AA_QR_REF_getVehicleCategory

a!queryRecordType(
  recordType: 'recordType!{9030da14-57d1-418e-94c7-4feccee2719c}AA REF Vehicle Category',
  filters: a!queryFilter(
    field: 'recordType!{9030da14-57d1-418e-94c7-4feccee2719c}AA REF Vehicle Category.fields.{357ad3b5-a7c5-42a6-835d-c653784f6065}id',
    operator: "=",
    value: ri!refCategoryId,
    applyWhen: a!isNotNullOrEmpty(ri!refCategoryId)
  ),
  pagingInfo: a!pagingInfo(startIndex: 1, batchSize: 50)
).data

The refCategoryId is an optional input.

Could you please tell me why I am getting this error?

    Hello Ritika,

    I noticed an error in the code, which is caused by a missing parenthesis "()" in the function call. The correct function call should be rule!AA_QR_REF_getVehicleCategory(). Additionally, even though refCategoryId is an optional input, you still need to pass it as it's the only required input. In this scenario, you can pass null().

    local!category: rule!AA_QR_REF_getVehicleCategory(refCategoryId:null())

    Hope it helps!

    Hi ,

    Thanks for that advise. It worked. But I am facing another error which I am unable to understand.

    The error is as below:

    Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error at function a!dropdownField [line 123]: AA REF Vehicle Category must be indexed by its corresponding record type fields or relationships

    The code after changes looks like this:

    What does this error mean and how can I resolve it?

    In the dropdown "Category," please adjust the choice labels and choice values. Instead of using the index() function, index the values in the same manner as you did for the "Condition" dropdown.

    choiceLabels: local!category[recordType!AA REF Vehicle Category.fields.fieldName],
    choiceValues: local!category[recordType!AA REF Vehicle Category.fields.fieldName]
