This code works using the Microsoft Graph Explorer using the SharePoint Search, but when I export it to a .NET Core App it seems to go wrong due to access issues. Am I missing something here?
var requests = new List<SearchRequestObject>()
{
new SearchRequestObject
{
EntityTypes = new List<EntityType>()
{
EntityType.Site
},
Query = new SearchQuery
{
QueryString = "tryingAgain"
}
}
};
await _graphServiceClient.Search
.Query(requests)
.Request()
.PostAsync();
Stack trace error:

What permission did you grant for the app? According to this documentation, the app need to have at least permission Sites.Read.All to search sites.

I tried to find a way to enable allowDiskUse to true for GridFS but couldn't find one.
You are perhaps missing the indexes that drivers are supposed to create automatically.
Ensure you are using the most recent driver release.
Upload another file to the same GridFS bucket. You can delete the file immediately afterward.
Check for index presence manually. See here under "indexes" for what should exist.
I had this error when I Used DownloadAsBytes.
The error was solved by Deleting the Database then letting the GridFs create the Database again.
I'm trying to create a folder on an Online SharePoint with the site url https://example.sharepoint.com/MySite
I really don't care anything about SharePoint lists, but I can't find any information towards a SharePoint API which hides this implementation detail from the consumer, nor any documentation which anticipates my needs well enough to tell me what I need to do, so I am struggling to work with the Lists.
At present, I just want to simply list whatever lists exist on my site. My site has some minimalistic content, so I expect in a world were everything has lists, there should be some lists involved and I should be able to somehow list them.
I have the following code:
using (ClientContext context = _authenticationManager.GetContext())
{
Web web = context.Web;
context.Load(web.Lists, lists => lists.Include(list => list.Title, list => list.Id));
context.ExecuteQuery();
foreach (List list in web.Lists)
{
_logger.LogInformation(list.Title);
}
}
I've been able to use the debugger and the console to confirm the AuthenticationManager is successfully generating an authentication token.
When the code executes, context.ExecuteQuery(); results in the following error:
[14:49:48 INF] Successfully requested new access token resource example.sharepoint.com for user someuser#somemail.foo <s:SharepointOrderContractExtractor.Clients.AuthenticationManager>

What am I missing and/or doing wrong?
How can I correct this?
With thanks to #arconaut for his question in the comments:
It seems the Authentication Manager only uses the domain, not the full URL in order to authenticate.
While my site URL was set to https://example.sharepoint.com/MySite, it should have been https://example.sharepoint.com/sites/MySite.
(I think I dropped "sites" from the configuration while trying to follow some documentation which may not have matched my version of Salesforce.)
In our project we have an HttpClient for outgoing connection with a strict timeout, and previously, I dealt with the timeout situation like all the tutorials suggested: by catching the TaskCanceledException. And it worked. But since recently (can't say the exact time, but about a month), the timeout started to cause the OperationCanceledException.
System.OperationCanceledException: The operation was canceled.

It's not a big problem to change all the catches to OperationCanceledException, but I'd like to know why? Does anybody know why HttpClient could switch the exception? I deploy the application locally using the VS2019 16.4.3 and IIS express. Net core 2.2
I found it.

Basically, in case of short timeouts there is a race condition that can cause OCE to happen. What it means is "we do not really know what exactly happen, and we do not care, so you shouldn't too".
