Public survey, error 404 Not Found, The specified key does not exist

EduardoC_ — Fri, 10 Jul 2020 15:28:20 GMT

Hello, I have a public survey created with Survey123, people were able to submit answers until yesterday, it started to appear an error when opening the link of the survey in the browser, the error says 404 Not found, Code: NoSuchKey, Message: The specified key does not exist; as you can see in the attachment.

Thank you.

Hi Eduardo,

Are you still having this issue? If so can you provide more information?

Are you using AGO or Enterprise, and if Enterprise what version of Portal and how is it configured?

What version of Survey123 Connect are you using, or are you using Web designer?

Did any changes occur to the folder, feature service, or form item in your organization content? Have permissions changed, groups or items been moved?

Regards,

Phil.

We started experiencing the same type of thing today. It is intermittent and only on some devices but the devices are random so iOS and some Android devices work, others don't, some work some times others not at all. We are using Survey123 Connect V3.11.123 on a feature service on AGOL but using a 10.8.1 oracle geodatabase in the feature service. feature service and survey are public. I have a support call in and will post if they find a solution.

I suspect it might be an indexing issue on one of the host cloud servers, it seems the error can't find the survey (the key). I would assume more than one server serves up these services and is load balanced so a poor index on one server would explain the intermittent issue but not why some people can not get to it at all.

When I look at the incoming data between midnight and 1:30 pm today we are at 483 screenings and yesterday same time frame was 642 so for sure we are missing people but about three-quarters are able to get to the survey. Very strange and frustrating.

@Anonymous User Could you look at the error below please? I believe the error points to a problem on the AGOL cloud servers, likely an indexing issue. It has since been fixed with no intervention on our side. If you look at the error it points to a host not finding the key (the survey). The host is given by the HostID and that host is one of Esri Inc cloud hosts. This message would come up 25% of the time, the rest of the time the survey came up and was fully functional. If the servers are load-balanced it would explain why it would work 75% of the time. Please take a look at the error and confirm that you would interpret it the same way?

We had a similar thing happen about 5 years ago with open data, it took ages to get to Esri inc and in the end, it was an indexing issue on the cloud side, it was manually reindexed and it was fine.

I just need confirmation on what the error means so we can document the outage.

Thanks

Hi @MelanieWawryk,

I am not sure on the cause of the exact error message below, but it does appear it could be related to an issue with the ArcGIS Online cloud service, that may have been caused by a service interruption.

As I don't have access to the ArcGIS Online server logs and organization details that you are using, I would strongly recommend you contact Esri Support, and your support case will go through to the AGO server team, and they can look into the specifics of the issue you encountered, which includes looking into the server logs, any service interruptions or outages with the cloud servers that may have occurred at that time you are mentioning below.

Regards,

Phil.

Thank you, I'm in Canada and you saved a ton of back and forth of trying to replicate the issue locally prior to it being sent to the Esri Inc AGO server team. Hopefully, this will satisfy local support to allow it to move forward.

Just experienced the same issue and there appeared to be a single corrupted/missing file on a local node of AWS Cloudfront that's used by the Survey123 website. Ours was only a partial outage based on which node the cellular and internet providers were directed to. Had to work extensively with Support to find the right teams to refresh the cache on that specific AWS Cloudfront server node successfully.

This "no such key" error message appeared for one of our surveys today. It appears that a call to support is required to get this addressed? Any other options?

MelissaJ_TX — Mon, 05 Apr 2021 18:22:18 GMT

We had to put in a support ticket. The S123 Webform/AGOL team had to force a cache update to the local AWS Cloudfront server that was impacted with the missing/corrupted S123 Webform file.

Thank you for the update. I submitted a support ticket with a reference to this thread.

@ChipBrownHBG @EduardoC_ just following up to see if you were able to resolve this issue with Esri Support?

Thanks for following up, @Anonymous User. I submitted a ticket and worked with support some, but the issue really resolved itself overnight. It appears that it is related to the cache updating on the cloud services (well beyond my understanding of it all) as @MelissaJ_TX found with her issue. I assume the cache updating something that happens on a regular basis.

Since it seems the cache corrects itself, could Esri create a more public-facing error message so users don't think the surveys are broken? I know it is in the fine print but users only see the 404 error.

Also, it seems to be happening to quite a few people, is there a way to capture the errors and force cache updates automatically on the AWS Cloudfront servers to minimize the downtime? Short of that could a bulletin be put out to support so reports of these go directly to the S123 Webform/AGOL team to resolve it without having to go through all the troubleshooting questions prior to it being escalated. It would save a lot of time and effort.
