We are facing 501 error when using the latest version of haystack-csharp library (version from 2019-03-11). We use it for data import to Skyspark (ver. 3.0.19).
Sometimes we get this error
ProjectHaystack.Client.CallNetworkException

As you can see it is just call of readAll(String filter). What could cause this error?

Hi Jan, can you provide some more details?
Is this reproducible?
Does it happen for all your calls or only some?
Can you figure out what the exact call is that is done to the SkySpark application (by using a packet sniffer for example)?
I am using the same library myself without any problems. There is a PR pending by the way for a fix in SkySpark 3.0.20, but that should not be related to your problem.

Hi Chris,
meanwhile, we had found the problem. We were using wrong url .../ui/project instead of .../api/project - typical copy&paste failure :)
