Attribute Rule Refinement: Extract Characters from one field, compare coded domain and return domain description

Hello

My goal with this rule is to get it to auto-populate our municipality field with a domain description when a user types in a parcel number.

I have assigned the Municipality_Codes domain to the Municipality field.

Here is what the Municipality_Codes domain looks like:

The first three numbers of the Parcel # coincides with the three numbers assigned to each municipality in the domain.

Here is the the Arcade expression that I was able to come up with using ChatGPT. It still does not work even if I try to use Calculate Field. I feel like the first 12 lines make sense it's when it goes through the looping is where it is not working.

// 1. Validate PARCELNO & extract prefix var src=$feature.PARCELNO; if (IsEmpty(src) || Count(src) < 3) { return null; } var prefix = Left(src, 3); // 2. Get the full coded value domain object var d = DomainName($feature, "Municipality"); if (d == null || d.type != "codedValue") { return null; } // 3. Loop through codes for (var cv of d.codedValues) { var codeStr = Text(cv.code); if (codeStr == prefix) { // 4. Return the matching description return cv.name; } } return null;

I went at it with ChatGPT again, this time it gave me this expression and it worked. Perhaps I just needed a fresh look at it.
