Unable to get local issuer certificate while connecting Apigee Edge from drupal based devportal

I am trying to connect Apigee Edge using developer admin credentials from a drupal9 based developer portal. Whenever I test the connection I get the below error from my local environment(Authentication type is OAuth).

Failed to connect to the OAuth authorization server. Check the debug information below for more details. Error message: cURL error 60: SSL certificate problem: unable to get local issuer certificate (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)).

Do we need to add any cert to authenticate Apigee Edge cloud from local?

It seems the error is due to the cacert as noted in the Drupal issue https://www.drupal.org/node/2481341

Installing the latest certificate should help.
