Error: Invalid Chai property: calledTwice

I'm seeing the error above when running unit tests. Can someone please help? I have sinon-chai installed. See my package.json:

      "@types/chai": "4.2.14",
       "@types/chai-as-promised": "7.1.3",
       "@types/query-selector-shadow-dom": "1.0.0",
       "@types/node": "14.14.36",
       "@types/sinon": "9.0.8",
       "@types/sinon-chai": "3.2.5",

That package.json snippet is not including sinon-chai (or chai, for that matter), it's including the DefinitelyTyped type definitions for Chai. Are you including the actual chai and sinon-chai elsewhere in your package.json?

Also, we won't really be able to help without seeing what your test code is doing - at least a snippet that's calling calledTwice and the part where you set up sinon-chai.
