X-Ray captureAWSClient DynamoDB DocumentClient didn't work

[polovi]

Is there some workaround for capture DocumentClient with xray except capture whole SDK?
Due to creating custom service provider this code didnt work.

const AWSXray = require('aws-xray-sdk')
const AWS = require('aws-sdk')
 
const client = new AWS.DynamoDB.DocumentClient({
  service: AWSXray.captureAWSClient(new AWS.DynamoDB({...}))
})

If service from configuration will be used as it is and not created again then captureAWSClient will be work. I also set everything up in my service and no configuration params ar pushed to DocumentClient constructor

A possible workaround would be to wrap the service client after you've created the DocumentClient.

const AWSXray = require('aws-xray-sdk');
const AWS = require('aws-sdk');

const client = new AWS.DynamoDB.DocumentClient({
  service: new AWS.DynamoDB({...})
});

AWSXray.captureAWSClient(client.service);

Seems that AWSXray.captureAWSClient(client.service) works as workaround

But there is problem if i use typescript that AWS.DynamoDB.DocumentClient.service is internal and not defined in d.ts file so I am not able to compile it

Any progress?

@polovi a workaround for your TypeScript issue is,

...
AWSXray.captureAWSClient((client as any).service);

which casts the client to any, just so you can access service on it.
