javascript – How to fix Lambda function timeout when interacting with DynamoDB using AWS SDK v3 in Node.js?
I’m building a serverless API with Node.js using AWS Lambda, and my function interacts with DynamoDB to retrieve data. However, every time I try to interact with DynamoDB, the Lambda function times out before the request completes.
I have correctly configured my Lambda function’s execution role with the necessary permissions, and I’ve ensured that the AWS SDK v3 (@aws-sdk/client-dynamodb
) is properly installed and initialized. Despite this, the Lambda function times out without successfully querying DynamoDB.
Here’s what I’ve done so far:
-
Configured the Lambda function timeout to 30 seconds, but it still times out.
-
I verified the permissions for the Lambda role, which includes access to DynamoDB.
-
I used
async/await
for handling asynchronous requests.
I expect the Lambda function to complete successfully and return data from DynamoDB without any timeouts.
-
I tried increasing the Lambda function’s timeout to 30 seconds.
-
I tried adjusting the read/write capacity of the DynamoDB table, but it didn’t solve the issue.
-
I expected the Lambda function to run without hitting the timeout and successfully retrieve the data from DynamoDB.
Task timed out after 30.01 seconds
const { DynamoDBClient, GetItemCommand } = require("@aws-sdk/client-dynamodb");
const client = new DynamoDBClient({ region: "us-east-1" });
const params = {
TableName: "MyTable",
Key: { "id": { S: "123" } }
};
exports.handler = async (event) => {
try {
const data = await client.send(new GetItemCommand(params));
return {
statusCode: 200,
body: JSON.stringify(data),
};
} catch (err) {
console.error("Error", err);
return {
statusCode: 500,
body: JSON.stringify({ error: "Could not retrieve data" }),
};
}
};
I’ve verified that the DynamoDB table exists and contains data for the provided id
, but the Lambda function still times out.
