[Dúvida] Dificuldade em rodar em modo headless

Consegue mostrar a sua estrutura de arquivos ? e também o arquivo onde o mocha está instalado ?

Pode mostrar o package.json tbm ?

Consegue me mandar o conteúdo do arquivo que está no node_modules>mochawesome>src>mochawesome.js ?

Copia tudo que tiver no arquivo e mande aqui por gentileza
