Información adicional
This is as designed. Arcade is a programming language needing to be authored to handle errors. In this particular case, the first feature in the table, which is used by the expression builder for verification, happened to have a whitespace in "$feature.location" which passed the validation. However, when subsequent new features are created, they may have a location without a whitespace, which results in a split returning one element instead of two. This is why the rule sometimes works and sometimes fails. So, a guard logic must be added regardless.Solución alternativa
Add error handling for cases where the locArray variable has 0 or 1 items. Refer to the example below.
"var MainLoc = text($feature.LOCATION)
var locArray = Split(MainLoc, " ")
if ( Count(locArray) < 2 ) { // error handling
return
} else { // existing code
var abrevTship = locArray[1]
return abrevTship
}"
