Type of Issue:

• Enhancement: New feature or request

Issue Creator Checklist

• This issue has been thoroughly documented below; a developer should be able to understand the issue by reading it.

Background

Our project is currently using Node version 12. Node 12 will run out of maintenance next year; see releases. We should upgrade to a version with longer support, 14.

Proposed Approach

Our node version is currently specified and locked using nvm at the top level of the project.
Our lambda functions are currently exclusively using Node 12.x runtimes.

All needs to be updated?

Value

Node 12 is nearing end of life. Moving to Node 14 now positions us to have a better supported product.

AC:

• Node 12 is replaced with Node 14 in all places using node, including lambdas.
• Wiki documentation has been updated.
