ExportVectorTilesTask IllegalStateError

[CristhianSanchez]

Hello,

We use ExportTileCacheTask and ExportTileCacheJob to export vector tiles as a basemap for use while offline. We have noticed that when performing simultaneous downloads:

Sometimes one of the jobs in progress fails with the error: ArcGIS.IllegalStateError(details: “Server job has failed.”). We wonder why this might be happening and if there are any recommendations we should follow to prevent this?

Thanks in advance.

Haven't heard back from our domain experts yet. A few things to clarify…

1. Are you exporting the tiles from an ArcGIS Enterprise server, or from a public ArcGIS Online service?

2. Are you using ExportTileCacheTask or ExportVectorTilesTask? i.e., are you exporting raster tiles or vector tiles?

    - if exporting raster tiles, what level ID range is being exported

    - if exporting vector tiles, did you set area of interest and max level

3. Do you know at minimum how many jobs in parallel would consistently trigger this error?

Hello Ting,

1.  ArcGIS Online service

2. We export both raster and vector tiles:

    - Raster tiles Level ID range: level 11 (min), level 18 (max)

    - For vector we set area of interest and max level through makeDefaultExportVectorTilesParameters

3. It's not consistent; I'd say 8 - 10 jobs.
