I have a website built on node 8.9.0 and hosted on Heroku, a recent root certificate used by Let's Encrypt expired. That's why I am not able to make external API calls.

Is there any way to fix this? I found one article which says to upgrade node to >9, but due to limitations and dependencies, I am not able to upgrade it. So is there any way to degrade this update just a temporary solution to make the site run, and I can upgrade the website side by side.

Basically, you need to "Configure the server to use the alternative certificate chain which can be requested from Let’s Encrypt with most up-to-date ACME protocol clients"
