mongodb - TypeError: Cannot read property 'match' of undefined

[cloudy tech]

I've deployed a next.js app in AWS Amplify and while it works fine on my local machine I'm getting this error when I try to access any of the /api/ route:

ERROR   Unhandled Promise Rejection     {
        "errorType": "Runtime.UnhandledPromiseRejection",
        "errorMessage": "TypeError: Cannot read property 'match' of undefined",
        "reason": {
            "errorType": "TypeError",

            "stack": [

            ]
        },
        "promise": {},
        "stack": [
            "Runtime.UnhandledPromiseRejection: TypeError: Cannot read property 'match' of undefined",

            "    at process.emit (events.js:400:28)",

            "    at processTicksAndRejections (internal/process/task_queues.js:96:32)"
        ]
    }

I'm sure it has something to with mongodb since the error is happening in MongoClient but I'm not sure what exactly the problem is. Please help.
