Hello everybody, When generating an html coverage report with nyc report --reporter=html I am getting the html files in a folder, but trying to open a specific file, the following error is occured:

Cannot read property 'start' of undefined
TypeError: Cannot read property 'start' of undefined

The text table report works and shows results, but the HTML is broken.

Research-Richtung
The error occurs in annotator.js at line 92 in annotateFunctions where 'start' is undefined. Investigate why the function metadata lacks this property. Check the data flow from nyc to istanbul reports, focusing on how coverage maps are built. Review issue comments for proposed fixes or additional context. Consider adding a null check or ensuring the function object is complete before annotation.
