Cannot find module aws-sdk client-sns

0 votes

I am getting this error when calling my lambda.

"errorType": "Runtime.ImportModuleError", "errorMessage": "Error: Cannot find module '@aws-sdk/client-sns'\nRequire stack:\n- /var/task/handler.js\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js", "trace": [ "Runtime.ImportModuleError: Error: Cannot find module '@aws-sdk/client-sns'",

import * as AWS from '@aws-sdk/client-sns';
import { JamaSnsMessage } from './models/jama';
import { region, snsTopicArn } from './utils/constants';
import { log } from './utils/logger';

const client = new AWS.SNS({ region });

/**
 * Publishes given SNS formatted Jama items to SNS topic
 *
 * @param {JamaSnsMessage[]} items
 */
export const publishItems = async (items: JamaSnsMessage[]): Promise<void> => {
  if (!items || items.length <= 0) {
    return;
  }

  for (const item of items) {
    const params = {
      /* eslint-disable */
      MessageStructure: 'json',
      Message: JSON.stringify(item),
      TopicArn: snsTopicArn,
      /* eslint-enable */
    };
    log.info(`Sending jama item: ${JSON.stringify(item)} to sns`);
    await send(params);
  }
};

export const send = async (params: AWS.PublishInput): Promise<void> => {
  try {
    const data = await client.send(new AWS.PublishCommand(params));
    log.info(`Item: ${JSON.stringify(params)} was published with id: ${data.MessageId}`);
  } catch (error) {
    log.error(`Error while publishing message ${JSON.stringify(params)}. Cause: ${error}`);
  }
};

This error occurs because the AWS SDK package named @aws-sdk/client-sns is not found in your Lambda function's node_modules folder.

To resolve this issue, you need to add the @aws-sdk/client-sns package to your Lambda function's dependencies.

You can do this by running the following command in your Lambda function's directory:

npm install @aws-sdk/client-sns

This command will install the required package and update the package.json file with the new dependency.

After that, you can deploy the updated code to your Lambda function, and the @aws-sdk/client-sns module should be found by your Lambda function without any issues.
