Hi @Amey-MSFT .
This happens with just one Application Registration.
When we triy to get a token with
const tokenProvider = await props.context.aadTokenProviderFactory.getTokenProvider();
const accessToken = await tokenProvider.getToken(value ?value:props.properties.url);
i get this error.
{
"odata.error": {
"code": "-1, System.AggregateException",
"message": {
"lang": "en-US",
"value": "One or more errors occurred."
}
}
}

That doesn´t say much.

I´ve deleted the client secret, deleted the SharePoint app. and still doesn´t work.

Hi @Amey-MSFT is there anything i can do in here. This error have become more often with new App Registrations.

Hello @juancardonabizagi ,
Since you deleted the client secret, ensure that the app has a valid client secret or certificate associated with it. If you're using a certificate for authentication, ensure that the certificate is properly uploaded to Azure AD and configured for the app registration.
Thanks!!
Let me know if further help is required.
