Also seeing the "API Error" on some of our datasets on our Open Data site, but not all of them, even though owners haven't been changed, these datasets are different sublayers out of the same ArcGIS Server services, etc. Developer Tools shows that for the erroring datasets, where the request is https://opendata.arcgis.com/api/v3/datasets/whateverhubidthisis/downloads?parameters=1234 the response is errors: message: "Not Found". (The previously mentioned https://od-jcwvgis.opendata.arcgis.com/datasets/8d4df0b309944ccf8b72bf0d279a168b_1/explore?location=... I see also has "Not Found" in Dev Tools for its download endpoint)
Taking a look at https://opendata.arcgis.com/api/v3/datasets, seems like that's where all Open Data datasets are, and at the very bottom it has a "last" page of https://opendata.arcgis.com/api/v3/datasets?page%5Bnumber%5D=1420043&page%5Bsize%5D=10 but going to that last page gets you a:
{"errors":[{"title":"Server Error","status":500,"message":"search_phase_execution_exception: [illegal_argument_exception] Reason: Result window is too large, from + size must be less than or equal to: [10000] but was [14200430]. See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level setting."}],"meta":{}}With this in mind, I tried searching for my erroring datasets in https://hub.arcgis.com and as you can guess, they're not showing up; my download-OK datasets show up, but not the API error ones.
Esri: I think you can try increasing your [index.max_result_window] index level setting for the Open Data/ArcGIS Hub site to see if this fixes the API Errors that we're seeing? Worth a shot.
Thank you!
