Problem

What problem are you trying to solve? What issue does this close?

Node 12 has reached its EOL and no longer provides any security support. Currently, our Github CI actions for ci, testing and Sentry sourcemap compiling runs on Node 12, as well as our Serverless user functions. We upgrade these to run on Node 14.

Partially closes #1811

Solution

How did you solve the problem?

• Upgraded GitHub Actions Node runtime from 12 to 14 on staging
• Ran through release checklist on staging
• Upgraded Serverless functions
• Tested out Serverless functions

Deploy Notes

For the lambdas, we will have to reconfigure the VPC and the environment variables and test for functionality after deployment, as the VPC configurations and environment variables are dropped when the runtimes changes.

As these lambda functions are meant for internal use, we do not foresee this having any public impact. The reconfiguration + tests should not take longer than an hour.

lgtm! just checking regarding the deploy notes, those are referring to the lambda functions and have nothing to do with our main app right?
