CSOM throwing random error

[Germán Torres]

Hi there!

I've been using CSOM Framework for several months without important problems... Since a few weeks ago, I've been getting "Error 429" sometimes when one of my processes executes. Due to the fact that sometimes it works fine and sometimes it doesn't, I don't know what the problem cause is.

The error I'm getting is this one: System.Net.WebException: The remote server returned an error: (429). at System.Net.HttpWebRequest.GetResponse() at Microsoft.SharePoint.Client.SPWebRequestExecutor.Execute() at Microsoft.SharePoint.Client.ClientRequest.ExecuteQueryToServer(ChunkStringBuilder sb)

For the record, I get this error when I try to see a Resource's assignments.

Thanks a lot.

Hi Germán, 429 normally means you are being throttled - are you making a lot of calls? This article explains throttling in SHarePoint Online which also applies to Project Online - https://docs.microsoft.com/en-us/sharepoint/dev/general-development/how-to-avoid-getting-throttled-o...

Best regards,

Thanks for your answer, Brian.

I'll see how I can customize my code so that it doesn't get throttled.
