can't add fields in friend's dynamodb using lambda - aws-lambda

Question

I've tried to set up an API gateway and IAM permission but I keep getting an error message when I test my lambda function.
"errorType": "Runtime.UserCodeSyntaxError",
"errorMessage": "SyntaxError: Cannot use import statement outside a module",
"trace":
"Runtime.UserCodeSyntaxError: SyntaxError: Cannot use import statement outside a module",
" at _loadUserApp (/var/runtime/UserFunction.js:98:13)",
" at Object.module.exports.load (/var/runtime/UserFunction.js:140:17)",
" at Object.<anonymous> (/var/runtime/index.js:43:30)",
" at Module._compile (internal/modules/cjs/loader.js:1138:30)",

" at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:71:12)",
" at internal/main/run_main_module.js:17:47"
My lambda function:
import * as AWS from 'aws-sdk';
AWS.config.update({
accessKeyId: 'key',
secretAccessKey: 'key',
region: 'us-east-1'
});
const documentClient: AWS.DynamoDB.DocumentClient = new AWS.DynamoDB.DocumentClient();
interface IEvent {
email: string;
firstName: string;
lastName: string;
}
exports.handler = async (event: IEvent): Promise<void> => {
if (!event.email) {
throw new Error('Candidate email is required.');
}
if (!event.firstName) {
throw new Error('Candidate first name is required.');
}
if (!event.lastName) {
throw new Error('Candidate last name is required.');
}
await documentClient.put({
TableName: 'honeypot-interview-contacts',
Item: event
}).promise();
};

You've got the error right there, actually: SyntaxError: Cannot use import statement outside a module. Try switching to require? And it looks like you're running TypeScript? I don't think the default Node runtime has built in support for TS, you might want to run the code through the TS compiler first, that should also handle the import error.
