Typescript error when testing diamond

[danielhursan]

Describe the bug I'm running into an error when adding a test for a simple diamond use case. From what I see, it all boils down to this method call

....
diamondCutFacet = (await ethers.getContract("DiamondCutFacet", diamondTemplate.address));
....
await diamondCutFacet.diamondCut(
            [{
                facetAddress: sampleFacet.address,
                action: FacetCutAction.Add,
                functionSelectors: SAMPLE_FACET_SELECTORS
            }],
            "0x0000000000000000000000000000000000000000", 
            "0x"
        );

Error encountered is the following

An unexpected error occurred:

It seems that only that particular call triggers the error and invokes the hardhat/types/runtime at some point I've also tried to add "type": "modules" in package.json, which triggers other errors and it's not a solution, because I can't change requires with imports for dependencies of hardhat-deploy.

To Reproduce Steps to reproduce the behavior:

1. Add a test for interacting with DiamondCutFacet contract
2. Attempt to call diamondCut() method
3. See error
4. If I comment out that first piece of code, error goes away.

Expected behavior I would expect any error related to my code, missing function or whatever helpful, but stracktrace points to some internal references. Not sure if it's a conflict between hardhat-waffle and hardhat-deploy-ethers, that I understand use hardhat-ethers behind the scenes, but different forks.
