# Digital Commerce SDK Troubleshooting

This topic provides hints and tips for troubleshooting and fixing common issues while using the Vlocity SDK.

## Example: SDK returns 0 or null, or does not return correct data

In the following code sample, the SDK does not return correct data even though the fields have data in the Salesforce cache:

The API response is as follows:

## Solution

The root cause of this issue is that the SDK maps fields in the following format:

```nolang
namespace__fieldname
```

You should ensure that the namespace specified in the SDK matches the one defined for the org.

```nolang
this.digitalCommerceSDK.namespace = "vlocity_cmt";
```

After setting the correct namespace, the SDK will return correct values from related fields.
