Send error: Polygon input not valid

JasonJordan00 — Fri, 17 Jan 2020 19:02:30 GMT

I have a survey using geoshape however we are getting an error if we try to collect a new record.

"24305: The polygon input is not valid because the ring does not have enough distinct points. Each ring much contain at least three distinct points."

The polygons we are drawing *definitely* have more than 3 points. We have many records preloaded into the feature service and most of the work is done using the inbox. Updating those records has been no issue in the field.

Other surveys using polygons have worked without a problem. Any ideas? Thanks!

Hi Jason,

Apologies for the delay. Without seeing the polygon, it's difficult to be able to see what the problem might be. One thing that may cause an issue is if the polygon self-crosses - Survey123 does not support complex polygons.

I've attached a screenshot of a typical polygon we've tried to input. I've tried all manner of shapes, and none seem to work.

Hi Jason,

Even, I have the same issue. I'm getting this error when trying to submit survey using survey123 mobile app (I'm using Android). But, when I submit the survey from web app, survey is getting submitted without any errro.

Are you able to fix.

Thanks,

Krish

I am having the same issue as well. It was working initially and in the last few weeks it has stopped working on all 3 survey's that use this feature. What causes this issue? All polygons contain at least 4 points and don't cross over.

FYI - I am using Survey123 Version 3.9.149 on an Android Samsung Tab A. I am also having the same issue using the Survey123 app on my desktop.

Has anyone found a resolution for this? I'm using 3.9.149 on iOS and Windows 10 and am seeing the same behavior. The app (iOS and W10) returns the error for a very simple polygon, but the web version works fine.

Here's the geometry of the polygon that I'm trying to submit with this survey submission.

"geometry": {
  "rings": [
    [
      [
        -117.19983194520817,
        34.062409431377134,
        0
      ],
      [
        -117.19395254305022,
        34.05785861838573,
        0
      ],
      [
        -117.20124815156996,
        34.05291644316269,
        0
      ]
    ]
  ],
  "spatialReference": {
    "wkid": 4326
  }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

It appears that the polygon isn't being closed. The first and last vertices are not the same. I looked through the log and didn't see anything else that raised a red flag.

Method is set to vertex. In another survey that works, method is set to sketch.

The spatial reference of the basemap used in S123 is different than that of the feature service that it's writing to (102100)

Any ideas?

James Tedrick‌ - this appears to be a bug. Should I go through support channels to submit bug report?

Re: Send error: Polygon input not valid

JamesTedrick — Tue, 09 Jun 2020 17:38:35 GMT

Hi Jimmy,

Is the geometry you are presenting taken from the applyEdits call or just from the logging of the feature prior to submittal? The internal representation inside Survey123 should auto-close and append a copy of the first vertex as the last vertex. In a basic test, I'm able to submit a 3 vertex polygon. Could I ask you to please file an issue with Esri Support to work out what the issue may be?

Re: Send error: Polygon input not valid

JimmyKnowles — Tue, 09 Jun 2020 18:00:50 GMT

James - thanks for getting back to me. This is after the applyEdits call. The error seems to be thrown due to the response it gets from AGOL. The only difference between my successful test (and I imagine your successful test) and the survey that gives an error is that we're trying to use an existing feature service. Based on the OP's description, he is also using an existing feature service.

Update: using Fiddler, I can confirm S123 is not closing the polygon, The applyEdits call that is sent to AGOL has an unclosed polygon.

We can open up a support ticket, but this appears to be a bug with using method=vertex for creating new polygons on surveys that hit an existing feature service.

JasonJordan00 — Fri, 12 Jun 2020 14:18:47 GMT

Jimmy, I can confirm that's the behavior I'm seeing on my end too. Definitely a bug using that method on existing services.

Re: Send error: Polygon input not valid

JenniferLidgett — Fri, 12 Jun 2020 14:23:42 GMT

I can also confirm that I am having the same issue when I use an existing service.

Re: Send error: Polygon input not valid

JimmyKnowles — Fri, 12 Jun 2020 14:34:10 GMT

Thanks Jennifer and Jason for confirming that you're seeing the same behavior. We have a ticket open with Esri support. If a bug gets filed, we'll report back with the bug number so you can follow its status.

We thought we had a work around, but that's not working either. We created a 'dummy' polygon layer that we added to a web map. We then used Arcade to create a custom expression that we added to the popup of that feature. That link passed the vertex coordinates to S123. I've confirmed that the coordinates passed are of a closed polygon, but once it's in S123, S123 doesn't close the polygon when submitting the feature.

Has anyone made any progress with this? To throw in a bit more of a twist, I have a survey that was working, made in Connect 3.9.120 that is now showing the same 24305 error in the mobile app Ver 3.9.149 on Windows 10 and iPad Mini 4 with IOS 13.5.1. The survey worked yesterday at field testing. The survey does point at an existing feature service. Other than some minor default and choice value changes, the only other change I made was to make the fields editable again in the feature service details visualization tab>pop-up>Attributes. I made that change by accident yesterday to the main service instead of the view which is exposed in Collector.

Thanks,

Jim

Jim, we don't have any additional updates. Our support case is still open. Esri has been unable to reproduce the error on their end. In fact, we can only reproduce the error in the affected feature services. If we publish a 'fresh' feature service and try to reproduce the error, we are unable to do so. If a bug gets filed or we get some other resolution, we'll update here.

Thanks for letting me know. FYI: In further testing, I found that it is only the freeform polygon tool in Survey123 that is causing the issue. The canned block/triangle tool is working and submits a polygon on my survey. Good luck with the issue. I'm under the gun a bit so am working to get a new service created. Thanks!

Re: Send error: Polygon input not valid

JimmyKnowles — Thu, 18 Jun 2020 14:39:24 GMT

Jim, it sounds like yours is a different issue. The main issue we're seeing is when using method=vertex that S123 is not closing the polygon. When using method=sketch and using the free sketch tool, you have to be very careful not to cross over your polygon. S123 only supports simple polygons. In our testing, it was very difficult to create a simple polygon (without crossing over itself) using the freeform tool and the Smart Shape tool didn't really create what we were trying to sketch.

JimmyKnowles — Mon, 22 Jun 2020 17:35:03 GMT

Just wanted to let folks know that we found what was causing the issue for us while working with Esri support. We had 'Optimize Layer Drawing' enabled for the layer in question. Once this was disabled, method=vertex worked. We'll let you know if a bug gets filed for this behavior.

UPDATE: This was attached to existing BUG-000127298 for our support case.

Hello Jennifer,

Did you find a solution? I have same problem too.

Jimmy!

Hey great find! I had optimized my layer and the same error occurred. When I turned it off, as you mentioned, it works again! THANKS!!!!
