AppAuthError { message: 'Error: certificate has expired', extras: undefined }

[REQUIRED] Describe expected behavior

I want to get the openid-configuration value like this ,

But

When the authorization_service_configuration.ts procedure execute the 77 line

it throws the exeception AppAuthError { message: 'Error: certificate has expired', extras: undefined }

[REQUIRED] Environment

• AppAuth-JS version: __"@openid/appauth": "^1.2.7"
• AppAuth-JS Environment (Node, Browser (UserAgent), ...): Node+ Electron.js_______
• Source code snippts (inline or JSBin)

 static fetchFromIssuer(openIdIssuerUrl: string, requestor?: Requestor):
      Promise<AuthorizationServiceConfiguration> {
    const fullUrl = `${openIdIssuerUrl}/${WELL_KNOWN_PATH}/${OPENID_CONFIGURATION}`;

    const requestorToUse = requestor || new JQueryRequestor();

    return requestorToUse
        .xhr<AuthorizationServiceConfigurationJson>({url: fullUrl, dataType: 'json', method: 'GET'})
        .then(json => new AuthorizationServiceConfiguration(json));
  }

Which certificate does the error point ? where is the certificate from?

if someone needs the answer to reslove Please tell me , thanks a lot

Start at authorization_service_configuration.ts line 77 and trace the xhr call through JQueryRequestor in the Node and Electron environment. Check the issuer's openid-configuration endpoint and its certificate details; done means identifying the failing certificate source and documenting a reproducible resolution or provider-side cause.
