Why does table.QueryAsync hardly ever work?

MattMiley — Sun, 12 Dec 2021 07:08:51 GMT

Here's my code:

  var table = await ServiceFeatureTable.OpenAsync(new Uri(AGOL_URL_Class.GetURL() + LayerID), null, null);
            table.Where = Where;
            table.OutFields = Fields;

var selected = await table.QueryAsync(Current_OBJECTID);

Its just like all the samples and it gets stuck almost all the time at QueryAsync

It just turns null after 60 sections then the code continues.

Could it be a timeout?

Check request with fiddler.

Hi,

Can you provide more information on this case since this shouldn't not happen. If you can create a simple reproducer and attach to the thread, I'll give a look for it and see what's going on.

I had some other layers querying at the same time, that's what was messing it up. It loads fine by itself but with other traffic going on it doesn't work.

Hi Matt,

I would a bit more information to be able to comment. Doing multiple queries from several layers shouldn't affect the query results.

I'll email the sample project to you, it has secured layers in it. I was wrong about it not working while loading other layers, it just doesn't work sometimes. its super annoying!!!
