Node web service keeps restarting (Error 502)

Hi, 2 days ago, we got notified that our node service was Out of memory. We tried upgrading our plan and redeployed the app. The app now keeps restarting after yarn run start—any ideas on resolving this issue?

When I try to access this web service from a browser, I get an HTTP Error 502.

Attaching a screenshot below for reference.

It may be running out of memory even with the upgraded plan. I’ll message you privately for more details.
