Can't run tests in dev environment

[Guitlle]

I wanted to learn from this repo so I cloned it but I couldn't pass from running tests. It seems to work with node 14 ( I couldn't use version 12). I did

yarn
yarn test:finance

and I got this error:

    Contract: Finance App

Any thoughts? What am I doing wrong?

I went to ..../aragon-apps/node_modules/hardhat/internal/hardhat-network/stack-traces/solidity-errors.js:108 and modified this function to this:

function sourceReferenceToSolidityCallsite(sourceReference) {
    if (sourceReference === undefined) {
        console.trace("DEBUG undefined source ref");
    }
    return new SolidityCallSite(sourceReference.file.sourceName, sourceReference.contract, sourceReference.function !== undefined
        ? sourceReference.function
        : solidity_stack_trace_1.UNKNOWN_FUNCTION_NAME, sourceReference.line);
}

Got this trace repeated several times:
