Node 18 tries to import aws-sdk

I’ve recently upgrade lamdba to node 18 and some of the functions seem to be throwing the following error. I am no longer using the ‘aws-sdk’ but the ‘@aws-sdk/client’ v3 versions

{
    "errorType": "Runtime.ImportModuleError",
    "errorMessage": "Error: Cannot find module 'aws-sdk'\nRequire stack:\n- /var/task/api/v1/onboarding/registerEmail/handler.js\n- /var/runtime/index.mjs",
    "stack": [
        "Runtime.ImportModuleError: Error: Cannot find module 'aws-sdk'",
        "Require stack:",
        "- /var/task/api/v1/onboarding/registerEmail/handler.js",
        "- /var/runtime/index.mjs",
        "    at _loadUserApp (file:///var/runtime/index.mjs:1061:17)",
        "    at async UserFunction.js.module.exports.load (file:///var/runtime/index.mjs:1093:21)",
        "    at async start (file:///var/runtime/index.mjs:1256:23)",
        "    at async file:///var/runtime/index.mjs:1262:1"
    ]
}
