Updating Nodejs, causing error in Lambda function

I was forced to update the node.js version, due to getting an error message saying that Lambda no longer supported the version referenced on this repository. Updated to version 22. When testing the Lambda on AWS I am getting the error included below. I am not a java dev so I would welcome updated app.js / package.json with corrected syntax.

Response:
{
"errorType": "Runtime.ImportModuleError",
"errorMessage": "Error: Cannot find module 'aws-sdk'\nRequire stack:\n- /var/task/app.js\n- /var/runtime/index.mjs",
"trace": [
"Runtime.ImportModuleError: Error: Cannot find module 'aws-sdk'",
"Require stack:",
"- /var/task/app.js",
"- /var/runtime/index.mjs",
" at _loadUserApp (file:///var/runtime/index.mjs:1087:17)",
" at async UserFunction.js.module.exports.load (file:///var/runtime/index.mjs:1119:21)",
" at async start (file:///var/runtime/index.mjs:1282:23)",
" at async file:///var/runtime/index.mjs:1288:1"
]
}
