API Error Open Data Download

Tony_J_Van_Der_Wielen — Wed, 09 Jun 2021 18:01:18 GMT

We started seeing and API error in the download section of our Open Data page. It looks like there are no reported issues on Esri's end https://status.arcgis.com/.

Has anyone seen this? Or do you know how to fix it? This is happening with all our content.

Thank you!

Tony

I'm having the same issue, Tony. I thought it might be a security thing for our agencies but the same issue occurs on my home computer.

I also have the same issue with some of our private layers. The data is point-in-time so I'm resolving by uploading the layers to AGOL rather than point to AGS service.

@Tony_J_Van_Der_Wielen Were you able to figure out why this is happening? I just encountered this same exact problem today. I have 10+ other Hub sites and I have downloaded data from them without an issue today as well.

Check the projection of the layer and if it is different to the local projection then disable the local projection in your hub site data setting. Else republish with your local projection.

Esri said it was a problem on their end of things and have resolved the issue. They would not give me the details, but if this is not resloved, I would open a ticket with them.

We just starting having this problem today. Logged a case with tech support, there appear to be a bug attached to this issue (BUG-000141153). No resolution yet. When using the Chrome browser developer tools, the 2 main errors I get are a 404 (Not found error) when I load the dataset's main download page - the data is in the AGO and is shared with the open data site is visible on the web map and within ArcGIS Online. The second error is when the user goes to download the data, the API error shows on the download options and and additional 500 (Internal Server Error) populates.

After further researching and looking into the network traffic it seems that when the Hub is trying to GET the Request URL for the layers on our open data site, it is not "getting" the entire URL. The layer ID is dropped (e.g. instead of https://opendata.arcgis.com/api/v3/datasets/1bc60d61f55644dc9320624a8fbea521_0 being the Request URL our HUB site is trying to GET https://opendata.arcgis.com/api/v3/datasets/1bc60d61f55644dc9320624a8fbea521 )

Which creates the first resulting in the "404 Not Found" error. The additional error is a "500 Internal Server Error" when you click on the open data download icon and an API Error message instead of being able to download the data.

I have been able to test this with another Open Data site on which our GIS data is accessible. Our site gets the API error but on the other site I can download the same data from the same feature services without issue.

How does this get resolved?

Hi,

I'm sorry to hear that you're having an issue with downloads. We're actively working on a bug fix where gallery cards are linking to the wrong dataset view. You may see that the dataset page will load, but downloads will not because it has the wrong layer information, as @MeghanLeavey pointed out. Meghan, can you provide a public URL for content on your Hub site that is having this issue?

Thomas,

Thank you for reaching out to me via the ArcGIS Hub Questions thread above. I have since resolved my issue, and it was caused by the Spatial reference used not being a standard WKID. In fact the Spatial reference used was a customized one base on WKID 27700. Because it did not match WKID exactly, Hub could not find the WKID definition required for the API to initialize for the download. When I disabled local reference, the API enabled and +-

Thanks for the additional information. Hub should be able to support numeric WKIDs like 27700. However, there may be a bug parsing the WKID that was supplied. We're investigating the issue right now. Can you please give a URL to an example item that is now working?

Hi @ThomasHervey1

Yes, our open data can be found here: https://gis-monmouthnj.opendata.arcgis.com/pages/open-data

Thank you!

Thanks @MeghanLeavey it looks like there is a routing bug from the gallery card. We're actively working on a fix and hope to release it as soon as possible.

If you need immediate access to downloads you can update the URL and adjust the layer information. For example, the routing resolution for "Building Footprints" will route to https://gis-monmouthnj.opendata.arcgis.com/datasets/fec0b3d813174cdfb766134315120460/explore?layer=0

You'll still see the view working correctly and downloads will work if you adjust by removing the query and adding "_0"

This issue is also affecting us, but it is not universally an issue on all datasets. Below is one example.

https://data.bellevuewa.gov/datasets/cobgis::bellevue-permits/explore?layer=0&location=47.589609%2C-122.160741%2C12.97

It is not an issue across the board though. The issue may be isolated to specific hives such as EYzEZbDhXZjURPbP.

Is there an ETA on when this will be fixed? We have quite a few members of the public who are trying to access our open data and are getting this error. I can confirm that the API does work when following @ThomasHervey1 method of adding the _0/explore string to the end of the url.

Glad to see it is not just us.

Re: API Error Open Data Download

ThomasHervey1 — Mon, 13 Sep 2021 18:10:34 GMT

We have verified that this is a bug and we are completing QA now. Will release it tomorrow mid-day EST during our normal weekly Hub release. Please stay tuned to the Hub changelog https://hub.arcgis.com/pages/changelog
Apologies again for the inconvenience and thank you for your patience.

Appreciate the response and look forward to seeing the resolution.
