Getting error at compile time

[sarahbenjamin]

I downloaded the React-Azure-maps-playground-master folder and ran npm install and npm run on the folder. That added the node_module folder.

I am using TypeScript React 3.9.6

When I run npm start. I get a compiler error like this

Starting the development server...
Failed to compile.

/react-azure-maps-playground-master/node_modules/jest-diff/build/diffLines.d.ts
TypeScript error in /react-azure-maps-playground-master/node_modules/jest-diff/build/diffLines.d.ts(8,13):
