How to fix the 401 error when trying to get dataverse data in SPFx webpart ?

Dattatraya Kamthe, Anita 60

I’m trying to connect to dataverse via an app registration in Azure AD but I’m always receiving HTTP 401 responses when I try to get data via the AadHttpClient object (referencing the custom app client id). I’ve enabled the ‘oauth2AllowImplicitFlow’ option in the app registration manifest and granted user_impersontate permission on Dynamics CRM. Also the webApiPermissionRequests were added to the package-solution.json file in the spfx project.

Has something been changed on how to connect to dataverse?

Hi @Dattatraya Kamthe, Anita，

After app registerion, you will need to consume enterprise APIs secured with Azure AD in SharePoint Framework. If you are using enterprise API, you could follow the steps to connect with spfx

Do i need to create azure function and secure it with azure AD? I have registered the application in azure AD. I have given permissions to this app on dynamic CRM api (Dataverse API) as user_impersonation. also assigned system admin security role this app in power apps admin center.

Hi @Dattatraya Kamthe, Anita，

To access the api through enterprise application you will need to consume API secured with Azure AD

Hi,

I have created SPFx web part. I have given the user_impersonation permission to registered app in package-solution.json under "webApiPermissionRequests". then i am using below code -

this.context.aadHttpClientFactory .getClient('mentioned app client id') .then((client: AadHttpClient): void => { resolve(); }, err => reject(err));

I have also approved the API permissions in SharePoint admin center. but still getting 401 issue.
