How to run serverless offline in my node project?

Question

I am a long time user of serverless, but only started using this offline plugin on my current project. The current project is a Node GQL server using Apollo and TypeORM that will eventually be deployed to AWS Lambda, but is only local for now while it is being built.

My issue is I cannot run the function due to the following error that occurs every time I try to run the handler in a browser:

offline: Failure: Cannot use import statement outside a module
/Users/bduffey2/projects/movies/movies-be/src/entity/CaseType.ts:1
import { registerEnumType } from 'type-graphql';
^^^^^^

I looked at the .build directory and it all looks good (no imports) so unsure if this is somehow trying to load the raw ts file or if that is a red herring. I am also not sure if this is an offline issue or typescript or what, just at a loss as to what to look at next after looking at this for the past couple hours. I do have several other projects using serverless and typescript that deploy correctly and run correctly with a local handler, just have not used serverless-offline before so unsure if I have misconfigured something or am doing something else wrong.

My env is macOS Catalina on Node 12.16.2. I am currently running serverless 1.67.3, serverless-offline 6.1.4, serverless-plugin-typescript 1.1.9 and typescript 3.8.3. Happy to provide any more details needed as I am unsure what to even try next. Thanks!
