The Function-supported Operation is having trouble implementing a modification related to Geohash/Geopoint - the Object Type requires a String format

Summary: My function-based Action that tries to set a GeoPoint as a Geohash property is failing with an error suggesting it was anticipating a string.

I have an Object Type with a String property that has been designated as a Geohash in the property editor. The field in the underlying dataset consists of strings representing lat,long pairs, formatted as '12.123456,34.345678'.

Subsequently, I have a function-based action for modifying Objects of that Object type. It is currently configured to accept a string as input (using the regex 

^-?[0-8]?\d\.\d+,-?1?[0-7]?\d\.\d+$
for Submission Criteria to ensure it adheres to the expected lat,long format). The Typescript function then assigns it to the Object Type as a GeoPoint like this:

@Edits(myObjectType)
@OntologyEditFunction()
public editMyObjectType(
    myObject: myObjectType,
    .....
    latlong?: string,
    .....
): void (

    .....

    let geopoint = latlong? GeoPoint.fromString(latlong) : undefined;

    .....

    const cols: Partial<myObjectType> = {
        .....
        coordinate: geopoint
        .....
    }

    Object.assign(myObject, cols);
}

This does not lead to any errors. When I hover over coordinate within the cols variable, the tooltip indicates that, based on the imported Object Type of which it is an example, it anticipates a value of type GeoPoint | undefined. Clearly, GeoPoint.fromString(latlong), where latlong represents a string, effectively stores a GeoPoint in geopoint (when not undefined).

Nevertheless, when attempting to submit the Action in the front end, I encounter the following error:

Failed to apply change.

Error: [Actions] PropertyTypeDoesNotMatch
Error ID: <a UUID>
Related values:

 - propertyTypeRid: Optional[ri.ontology.main.property.<another UUID>]
 - expectedType: Optional[ValueType{value: PrimitiveWrapper{value: STRING}}]
 - actualType: Optional[Value{value: GeohashWrapper{value: 12.123456,34.345678}}]

The value at the end, 12.123456,34.345678, consistently corresponds to whatever is entered into the latlong field under consideration.

It seems that the Object Type is foreseeing receipt of a string from the function, even though in the Typescript editor it anticipates a GeoPoint and generates an error if a string is attempted to be provided. Why is this discrepancy occurring?

Edit: Furthermore, the function operates smoothly during testing in the Live Preview of the Typescript editor, producing an Object with attributes such as coordinate: 12.123456,34.345678.

Edit 2: I understand now that a GeoPoint is not simply a lat,long string but rather a structure containing distinct lat and long values. This raises the question: why, in TypeScript, does it interpret the coordinate property of myObject as a GeoPoint initially? Why is it not permissible to assign it a string?

Answer №1

After testing your code on a basic object type with the properties id (string), name (string), and location (geohash), I can confirm that it runs smoothly without any issues. I have reviewed the type signatures in your code and believe there are no errors present. However, there are a few things I recommend double-checking:

  1. Ensure that the property type is indeed a geohash and that there are no indexing problems associated with that specific object type.
  2. Confirm that the Action form fields have the correct types specified.
  3. Try creating a no-code Action to see if it achieves the same result as the function-backed Action you are attempting to use.

Basically, my suspicion is that the issue may not lie within the code itself but elsewhere.
