Issue Accessing Organization Service

[DivyaYeddula]

{"An HttpListenerException occurred while listening on http://localhost:5017/login/ for the system browser to complete the login.

@DivyaYeddula Need a bit more to work with here. Can you tell us the following: What sort of application is this ? (Windows client/Service/ API service / Function / etc. ) What sort of authentication are you using here? Are you using a connection string or one of the constructors? Can you provide us with a sanitized version of your connection code?

Also, the root error seems to be a file in use Error - "The Process cannot Access a file because its being used by another process", Did you provide a token cache file name and have that open in another tool?

thanks

Hi Team,

We are using client side Blazor. Server side AspNetCore net6.0. Using Below connection sting and ServiceClient.

@.**@.;url=****;ClientId=****;ClientSecret=*****;RedirectUri=http://localhost:5017/login;loginPrompt=Auto

ServiceClient client = new ServiceClient(CRMConnectionString); ApplicationContext.ClientContext["OrganizationServiceProxy"] = client;

@.***

Here after 10-20 requests automatically giving the error, even passing the connection sting not able to create the instance of organization service client.

Thanks & Regards Divya.

Last time I tried using Dataverse Service client with WebAssembly a few months ago it was not supported. Server side Blazor should work though.

Hi Team,

We are using ASPNET CORE net6.0 for server side, using Web API we are calling to server side.in this we are using Microsoft.PowerPlatform.Dataverse.Client DLL to connect the Dataverse. It is connecting to Dataverse up to 10-20 requests after that it is disconnecting.

At that time, we are getting Failed to connect to Dataverse exception.

We are connecting like this below

string CRMConnectionString = string.Format($@"AuthType=OAuth;Username={username};Password={password};url={URL};ClientId={appID};RedirectUri=http://localhost:5017/login;loginPrompt=Auto");

ServiceClient client = new ServiceClient(CRMConnectionString);

Thanks & Regards Divya.

@DivyaYeddula a few things:

You're using a User / Password auth flow with LoginPrompt=Auto in a WebSite. Patten wise, this is going to get you into trouble as if MSAL, for any reason, decides that it needs user intervention your site is going to hang as its going to try to pop a user dialog for action. -

This IS the error you're seeing above. MSAL is trying to pop a user dialog.

If what your trying to do is capture the user ID of the user connecting to the website and use that as the user to connect to dataverse, you would need to manage auth on your own (not use the onboard system) and do a token exchange / On Behalf of authentication flow.

If you're trying to get the website an identity to talk to dataverse with, then you should use an App Identity instead of a user identity. You can use a Client Secret flow, or a Client Certificate flow for this.

Also are you creating a new connection (calling new ServiceClient(...) ) on each action from the page? If so I would suggest that you create a copy of the connection your going to use during startup and only recycle that if the connection fails.

Thanks

@DivyaYeddula Im going to close this issue, assuming that your going to shift over to using App Identities. if your still having issues, please feel free to reopen it or create a new Issue.
