Logger doesn't work

[create1st]

The logger function incorrectly assumes that you provide additional information and fails since a call to the logger in debug mode doesn't always carry additional information.
/Users/create/work/lambda-sns/node_modules/@vendia/serverless-express/src/logger.js:43 ...additional.map(lazyPrint) ^ TypeError: Cannot read properties of undefined (reading 'map') at Object.debug (/Users/create/work/lambda-sns/node_modules/@vendia/serverless-express/src/logger.js:43:23) at getFramework (/Users/create/work/lambda-sns/node_modules/@vendia/serverless-express/src/frameworks/index.js:13:9)

I have around 50 APIs built using @vendia/serverless-express and all of them stopped working suddenly after a redeployment. After spending a day troubleshooting, I found out that the logger.js has been changed in the latest version to use "...additional.map(lazyPrint)". This was causing following error when invoking the API:
{
"errorType": "TypeError",
"errorMessage": "Cannot read properties of undefined (reading 'map')",
"stack": [
"TypeError: Cannot read properties of undefined (reading 'map')",
" at Object.debug (/var/task/node_modules/@vendia/serverless-express/src/logger.js:43:23)",
" at getFramework (/var/task/node_modules/@vendia/serverless-express/src/frameworks/index.js:13:9)",
" at configure (/var/task/node_modules/@vendia/serverless-express/src/configure.js:22:35)",
" at Object. (/var/task/index.js:6:19)",

" at Module.require (node:internal/modules/cjs/loader:1098:19)",
" at require (node:internal/modules/cjs/helpers:108:18)"
]
}

I will revert back to version 4.10.1 for now, but above error is a blocker issue for the latest version. My lambda hander code is as below:
exports.handler = serverlessExpress({ app, logSettings: { level: "debug" } });

@create1st @anishsam thanks for the report. This should be fixed in 4.10.4 thanks to @H4ad
