# Data Quality assessment directly fails for all monitored fields but not for all users

## Symptoms

When running a data assessment on any record, **System Administrators** can complete the process successfully, while **regular users** immediately receive a failure message from the score meter.\
This behavior typically indicates a **permission issue**.\
Since the failure occurs only a few seconds after triggering the assessment, it likely relates to **authentication when accessing the Delpha Backend**.

#### **Delpha Debug logs**

When Delpha Support reviews debug logs on your org, they will look for entries similar to the following:

```apex
13:45:55.1 (335967743)|CALLOUT_REQUEST|[164]|System.HttpRequest[Endpoint=callout:delpha__delpha_AWS/global/v1/launch, Method=POST]
13:45:55.342 (342699239)|NAMED_CREDENTIAL_RESPONSE|NamedCallout[Named Credential Id=null, Named Credential Name=null, Status Code=0, Content-Type=null, Response Size bytes=0, Overall Callout Time ms=0, Connect Time ms=0, Interceptor Time ms=0
13:45:55.1 (343571256)|EXCEPTION_THROWN|[164]|System.CalloutException: You don't have read perissions on the User External Credential object.
```

## Root Cause

The error message —

> *You don't have read permissions on the User External Credential object.*\
> — indicates that the affected user lacks the required **read access** to the **User External Credential** object.

## How to fix

[Grant the affected user **read access** to the **User External Credential** object, either by:](/delpha-for-salesforce/delpha-setup/extra-tasks/check-my-org-settings.md#make-sure-all-delpha-users-can-access-user-external-credentials-object-mandatory)

* Updating the user's **profile**, or
* Assigning a **permission set** that includes read access to this object.
