Arcade expressions not working in pop-ups

SepheFox1

For some reason, the arcade expression I am using to convert wind directions from degrees to compass rose letters, which works perfectly in Map Viewer is not working properly in Dashboard. When a feature is identified on, the pop-up always shows the wind direction as "N", no matter what the actual compass value. In Map Viewer it converts the compass direction to the correct corresponding letters. Oddly, it also works correctly in Dashboard when that  same layer is added to a "Details" window, with the wind direction being displayed with correct compass directions, such as N, NE, S, SE, etc.

The expression I am using is:

var lookup = ['N', 'NNE', 'NE', 'ENE', 'E', 'ESE', 'SSE', 'SSE', 'S', 'SSW', 'SW', 'WSW', 'W', 'WNW', 'NW', 'NNW', 'N']
lookup[ Round(Number( Split( Text( $feature["WIND_DIRECT"] / 11.25), '.')[0]) / 2)]

That does seem odd that your expression wouldn't work in certain settings.

I really like the concise approach you've got, but could you try it as a series of conditional statements instead, to see if that works any better?

var d = $feature["WIND_DIRECT"];
var outstr;

if (d < 11.25){
    outstr = 'N'
} else if (d < 33.75) {
    outstr = 'NNE'
}
... and so on.

Or perhaps get your lookup index a little simpler?

var d = Floor(($feature["WIND_DIRECT"]+ 11.25) / 22.5)

var lookup = ['N', 'NNE', 'NE', 'ENE', 'E', 'ESE', 'SSE', 'SSE', 'S', 'SSW', 'SW', 'WSW', 'W', 'WNW', 'NW', 'NNW', 'N']

return lookup[d]
