Feature Info widget: "The information for this feature could not be displayed"

[HannahWilson3]

I'm using the Feature Info widget to display popup info for a couple tables, and it's giving me the error "The information for this feature could not be displayed". 

• This is different from the "no data" message.
• The error occurs whether or not a feature is selected.
• In the widget configuration, data source is configured for "default", not "selected features"
• The popup contains Arcade expressions and is working fine in map viewer.
• This error is occurring for 2 of 6 views in my app (the views show different web maps with different themes; each map has a table connected to a Feature Info widget. Tables in each map are from the same hosted table.) All the Feature Info widgets are configured similarly - four are working fine, but two are showing this error.
• When I googled the error, the only hit was for this bug: BUG-000143889 for ArcGIS Online
• I'm using ArcGIS Enterprise 11.3

The functioning popup in Map Viewer:

Similarly configured widget working in a different view (comes from the same hosted table in a different web map):

This might not be the answer, but are the non-working pop-ups created with Arcade content blocks (this is different from Arcade attribute expressions)? You mention expressions in your post, but I figured I'd ask since I've had problems displaying Arcade content blocks before with other widgets, though the result was a blank pop-up, not an error.

If you're using Arcade content blocks, try removing them and adding something "simpler" like a field list, and see if your feature info widget works then.

It's not using Arcade content blocks - just attribute expressions incorporated into a text block.

Here are the expressions used:

{expression/expr0}:

var awards = FeatureSetByName($map, "Livable Communities Grant Awards")
var districts = FeatureSetByName($map, "Met Council Districts")

// Filter for the district polygon corresponding to the district in this table
// should be a featureset with one feature
var thisDistrictFS = Filter(districts, "MCDIST = " + $feature.mcdist) 

// Get the feature from the featureset
var thisDistrict = First(thisDistrictFS)

// Find award points within the district feature
var districtAwards = Intersects(awards, thisDistrict)

// Create list of the award categories
var awardTypes = []
var awardList = ""
for (var f in districtAwards) {
  Push(awardTypes, f.CATEGORY)
}

// Clean up the list
awardTypes = Distinct(awardTypes)
awardTypes = Sort(awardTypes)
for (var f in awardTypes) {
  awardList += awardTypes[f] + TextFormatting.NewLine
}
awardList = Replace(awardList, "TBRA", "Tax Base Revitalization Account (TBRA)")
awardList = Replace(awardList, "LCDA", "Livable Communities Demonstration Account (LCDA)")
awardList = Replace(awardList, "LHIA", "Local Housing Incentives Account (LHIA)")
awardList = Replace(awardList, "TOD", "Transit-Oriented Development (TOD)")
awardList = Trim(awardList)

return awardList

{expression/expr1}:

// Convert big numbers to $1.7B, etc
var amount = $feature.lcaawardtotal
var millions = "$" + Round(amount / 1000000, 1) + "M"
var billions = "$" + Round(amount / 1000000000, 1) + "B"
var thousands = "$" + Text(amount, "#,###")
When(
  amount >= 1000000 && amount < 1000000000, 
  millions, 
  amount >= 1000000000,
  billions,
  thousands)

Incorporated into the text block:   

 {lcagrantsawarded} grants awarded through the following programs:

 {expression/expr0} 

 {expression/expr1} in grants awarded since 1996
