spec.ts error Debug Failure. False expression: Expected fileName to be present in command line

```
Oops...we found an error preparing this test file:

cypress/integration/spec.ts

The error was:

Error: Could not load /Users/gleb/git/svelte-ts-example/cypress/integration/spec.ts: Debug Failure. False expression: Expected fileName to be present in command line

This occurred while Cypress was compiling and bundling your test code. This is usually caused by:

- A missing file or dependency
- A syntax error in the file or one of its dependencies

Fix the error in your code and re-run your tests.
```

Cypress v5.3.0

To see
```
npm install
npm run build
npm run test:local
```

Start by running npm install, npm run build, and npm run test:local, then inspect cypress/integration/spec.ts and the resulting Cypress compilation error. The issue is resolved when this test file loads and runs without the “Expected fileName to be present in command line” failure.
