Server not starting: Argument of type 'unknown' is not assignable to parameter of type '{}'.

[cjycathy]

I've been following the instructions from the readme, and run on the ubuntu of Windows Subsystem for Linux, but at the point where I'm trying to run the app locally with npm run start, I'm getting this error:

the EnrichmentPipeline.ts(75,34):

response[Object.keys(e)[0]] = ets[Object.keys(e)[0]];

Any help is very much appreciated!
