Arcade referencing original feature broken after update

jmaxwell_braun — Thu, 02 Oct 2025 21:43:03 GMT

We are getting errors for fields with Arcade calculated attributes after the Field Maps 2025.2 update. It appears to only affect expressions that use the $originalFeature variable. The error message is vague: "10 attributes failed". Was there anything in the latest update that would cause this? Thanks

Edit: Esri has determined this is a bug. BUG-000179854, Description: The $originalFeature function fails when creating a new feature in ArcGIS Field Maps version 25.2, but editing the existing feature is successful.

Hey @jmaxwell_braun

Would it be possible to show a bit of the code? There may have been a depreciation that is causing this.

Hi Cody, here's an example.

//sets value of calculated coordinate field to null only if the location of the point is edited //if only attributes are edited, the coordinates remain the same if(!IsEmpty($originalFeature)) if(Geometry($originalFeature).x != Geometry($feature).x) return null else return $feature.UTM_X else return $feature.UTM_X

The calls just started coming in from staff that multiple Arcade expressions are failing for us after last night's update, and they cannot work as a result. 😞 I'm not sure what to do so I'm posting here in hopes of adding some urgency to this situation.

I opened Esri case number 04012489. For me it only affects certain expressions. For now I'm just disabling them so our field staff are able to work.

@jmaxwell_braun can provide some additional information to help us understand the issue a bit more.

What platform(s) are you seeing this error?
Occurring while using connected map, offline, or both?
Is the expression failing only when updating an existing feature?

@IngridHogle can you please provide some additional details.

What platform(s) are you seeing this error?
Occurring while using connected map, offline, or both?
Are the expressions being used in a pop-up, form, or elsewhere?
Can you share examples of expressions that are failing?

@DougMorgenthaler , it's happening on iOS with Field Maps logged into ArcGIS Online. Online only, have I have not tried offline. Seems to only happen when creating new features.

Thanks @jmaxwell_braun for the updated info.

My recommendation is to test whether the feature geometry has changed in comparison to the field values.

var fx = $feature.UTM_X var fy = $feature.UTM_Y var G = Geometry($feature) if( G.x != fx && G.y != fy ){ return { result: { attributes: Dictionary('UTM_X',G.x,'UTM_Y',G.y) } } } /* Note: the code above will update both fields with the changed values if there are values that have been updated in the field. */

That way it will only need to compare the latest changes to the geometry change. If there is a change it will update accordingly.

I was able to identify that for us, anyways, it is sloppy Arcade expressions I wrote in forms that are causing errors in Field Maps 25.2.0. These are of two varieties:

1. In one Arcade expression, I declared a variable twice (var BlahBlah = "this", then later var BlahBlah = "that"). This worked without errors in Field Maps 25.1.0, but failed in 25.2.0. Removing the second "var" statement, so it reads var BlahBlah = "this, then later BlahBlah = "that", fixes the issue.

2. In multiple Arcade expressions, I invoked $originalFeature without first using an If statement to make sure I was within $editcontext.editType =='UPDATE'. This worked without errors in Field Maps 25.1.0, but fails in 25.2.0. It makes logical sense to me that it would fail, since $originalFeature does not exist (there is no original feature) in the context of $editcontext.editType == 'INSERT'.

We are getting this issue in any Arcade calculated expressions within Field Maps Designer that call $originalFeature at any point (which is quite a few of them). The issue can be completely isolated from any other intrinsic functions/variables.

Arcade exceptions are thrown whenever $originalFeature is referenced, including something as simple as

var test = $originalFeature;

and nothing else in the expression.

Re: Arcade referencing original feature broken after update

IngridHogle — Thu, 02 Oct 2025 20:44:46 GMT

Can you try putting your expression inside an edit context condition like this (filling in an existing attribute for what I named value)?

var test = ""

//if this is a new feature

if ($editcontext.editType == 'INSERT') {

test = "new feature test";

// if this is NOT a new feature,

} else if ($editcontext.editType == 'UPDATE'){

test = $originalFeature.value;

}

return test

alexnJSI — Thu, 02 Oct 2025 20:49:44 GMT

I did try wrapping any calls to $originalFeature inside of a check for an UPDATE context, but that didn't seem to resolve the error. The code:

if ($editContext.editType == "UPDATE") { var test = $originalFeature; } return false;

It does make sense to me that the variable would only be non-null and accessible outside of an INSERT context, but even an explicit wrapper for an UPDATE state produces the same error:

[ARCADE] Expression failed to evaluate:
Name: expr9
Error: invalidArcadeExpression(details: "Arcade evaluation error. Evaluation_error_code::field_not_found Line: 1")

Re: Arcade referencing original feature broken after update

IngridHogle — Thu, 02 Oct 2025 21:08:26 GMT

I've never seen $originalFeature used by itself, so this is out of my league. I always use $originalFeature.something to get some information about the original feature, such as an attribute value, shape area, shape length, or x/y coordinate.

Re: Arcade referencing original feature broken after update

alexnJSI — Thu, 02 Oct 2025 21:58:52 GMT

We are also using it in that context, specifically to assess whether or not users have selected a different dropdown menu option. The example was just to simplify it as much as possible.

Regardless of whether or not we are calling $originalFeature.attribute or even just $originalFeature on its own, the error persists. Any calls to $originalFeature in any context are what is causing the bug.

IngridHogle — Thu, 02 Oct 2025 22:25:43 GMT

Roger that. Good luck! I feel lucky I was able to get all of my Arcade expressions working in 25.2.0 by just cleaning them up a bit last night. There have been no phone calls from the field today. Phew!

Feel like I'm going crazy a bit. Had seen this thread so though it might be related

Get loading icon and no form when creating a new feature from template
Arcade has a mix of $originalfeature, edit mode = insert, if statements, GetUser($layer).username, now(). Using variables and accounting for if inserting or updating i.e. no original feature reference on insert
Remove the arcade, form starts working
Add the same arcade calculations back in, form continues to work

Suggests there was some temporary performance hiccup but there's no other indications e.g. everything worked fine on 25.1, ArcGIS Online, and 25.2 when interacting with the layer outside of creating a new feature.

@IngridHogle Can you elaborate on your first Arcade issue? Maybe provide an example? I am having a similar situation. Post update I had two issues, both exclusive to Field Maps (all worked fine the web maps). The first was with editing the form in the Field Maps designer...I got generic error messages saying it couldn't be saved because there as a problem. I removed all of the fields from a group a and re-added them and that fixed it.

My second issue, which your post might speak to, involves an if/else statement to declare a variable in a pop-up. It uses html and works just fine in the web map as-written, but with certain templates it shows an error for the pop-up in Field Maps. It's generic (ArcGIS.InvalidCallError error 1), but I've narrowed it down to the logic around declaring a variable.

Re: Arcade referencing original feature broken after update

IngridHogle — Wed, 08 Oct 2025 23:28:56 GMT

@SFM_TravisBott , I have not yet tackled the pop-up errors we're getting, since they are not actually causing problems. So I'm not sure this will be helpful. My issue with $originalFeature was that I had superflous lines of code in my Arcade scripts, double-checking that no $originalFeature existed when edit context was INSERT, for example. Removing these resolved the issue.

My original code (works in 25.1.0)

if ($editcontext.editType == 'INSERT') {

// like really truly it did not exist before

if (IsEmpty($originalFeature)) {

return Today();

} else {

return $originalfeature.invdate;

}

} else {

return $originalfeature.invdate;

}

My cleaned up code (works in 25.2.0)

if ($editcontext.editType == 'INSERT') {

return Today();

} else {

return $originalfeature.invdate;

}
