Silent Refresh not initiating token refresh request

[BhanuGunda]

Describe the bug Calling mgr.signinSilentCallback() the backend api token refresh request is not triggered

To Reproduce Configurations made:

{ authority: ${environment.Authority}/, client_id: environment.clientId, client_secret: ${this.envService.clientSecret},
redirect_uri: ${this.envService.clientRoot}/auth-callback?auth=authc, automaticSilentRenew: true, silent_redirect_uri: ${this.envService.clientRoot}/auth-callback?auth=refreshToken, post_logout_redirect_uri: ${this.envService.clientRoot}/logout, response_type: 'code', response_mode: 'fragment', loadUserInfo: false, filterProtocolClaims: true, scope: environment.clientScope, extraQueryParams: { resource: 'sfr_web_dev' },

  metadata: {
    issuer: `${environment.Authority}`,
    authorization_endpoint: `${environment.Authority}/oauth2/authorize`,
    userinfo_endpoint: `${environment.Authority}/userinfo`,
    jwks_uri: `${environment.Authority}/discovery/keys`,
    end_session_endpoint: `${environment.Authority}/oauth2/logout`,
    token_endpoint: `${this.envService.clientRoot}/token`,
  }

Expected behavior Backend api call should get initiated on calling silent refresh(). It is not triggering backend apicall. No error is shown

Have you tested this in the VanillaJS sample app? Last time I checked, signinSilentCallback is working properly there. There's not enough info above to know why you might be having problems.
