jest scripts failing with exit status 1

I have a couple of test scripts that are failing after the tests are all passing successfully and not sure the reason. I've searched the web with no solution that resolves the issue.

Here is the output from the log after the execution of the script (npm run patch-coverage)

I've tried a few suggestions from GitHub

Can anyone provide a solution to resolve the errors?

Update

I created a simple test as follows and I still get the same error after running the patch-coverage. Could it be the patch-coverage configuration?

describe('186-add-new-locales', () => {
    test('Empty test', async () => {
        const x = 9;
        const y = 5;
        const z = x * y;

        expect(z).toEqual(45);
    });
});

Update (Feb. 6/24)

Upgraded npm to 8.19.4 and node to 16.20.2 - error no longer appears. Does this mean there is a version problem?

Solution

So the problem was the coverage as one line of redundant code that would never be hit so removed that code block and reran the coverage script. Got 100% coverage.

Checked the lcov report that identified the line(s) not being covered.
