Based on what I've observed, even if you don't specify a reporter, Playwright defaults to a built-in one. Instead of using `reporter: [['list']]`, try switching to either 'dot' or 'json' and see what results you get. The 'dot' reporter provides minimal console output, which is more suitable for CI environments, while the 'json' reporter outputs to a file. Since you are running this in Azure Functions, the verbose output from the 'list' reporter might be causing issues. Please test both options and let me know which one works for your deployment.
