AADSTS900971: No reply address provided. on SPA with http://localhost as redirect_uri

Question

Hello,

I am currently starting a Vue SPA application to join MS PowerBI and wanted to authentication with Microsoft.

In azure portal, we registered an application client as SPA and we gave http://localhost as redirect URI.

Then, on my view app, I run this code:

  const formUrl = `https://login.microsoftonline.com/${values.tenantId}/oauth2/v2.0/authorize`
  const params= {
    client_id: values.clientId,
    redirect_uri: "http://localhost:3000",
    response_type:"code",
    response_mode:"query",
    scope:"https://analysis.windows.net/powerbi/api/.default",
    state:"mystate",
    prompt: "consent"
  }
  const url = new URL(formUrl)
  Object.keys(params).forEach(k => url.searchParams.set(k, params[k]))
  window.location=url.href ;

However, the login page always answers AADSTS900971: No reply address provided.

What can I do?

Hi @François DAMBRINE

When you request the authorization URL, you will be redirected to the login page. Decode the authorization URL in the browser and find the redirect URL to see if it exactly matches the redirect URL you configured in the Azure portal.

Hope this helps.
