После исправления моих проблем у меня осталось только несколько ошибок.
eslint: error Parsing error: The keyword 'const' is reserved but I cannot use ES6
Признанное исправление, похоже, заключается в применении ES6 Мое приложение работает на AWS Lambda Node 12 и не работает с синтаксисом ES6, потому что тогда я получаю
"errorMessage": "Must use import to load ES Module: /var/task/lambda.js\nrequire() of ES modules is not supported.\nrequire() of /var/task/lambda.js from /var/runtime/UserFunction.js is an ES module file as it is a .js file whose nearest parent package.json contains \"type\": \"module\" which defines all .js files in that package scope as ES modules.\nInstead rename lambda.js to end in .cjs, change the requiring code to use import(), or remove \"type\": \"module\" from /var/task/package.json.\n",
"code": "ERR_REQUIRE_ESM",
Как я могу это исправить? Можно ли как-то игнорировать правило const?
