Cause and solution to this Salesforce validation or deployment error

Explanation of the error

You may come across this Salesforce validation (or deployment) error in a scenario where in your source environment you've made a reference (or references) to username(s) that don't exist in the target environment.

The returned error would be:
Cannot find a user that matches any of the following usernames: <xxx>; remove the user from the component being deployed or create a matching user in the destination organization. - where <xxx> usually refers to a user's email address.

Based on our observations, these are the metadata types that could throw this error: WorkflowOutboundMessage, ApprovalProcess, Dashboard, ReportFolder or CustomSite.

Resolution

Based on the message returned by Salesforce, they're suggesting you to remove the username <xxx> from your deployment package, and then to try to re-deploy again to the target environment.

Alternatively, you can create that user (with the correct username) in your target org first, and then re-attempt the deployment of your original package.

But if the user already exists in the target org (so there's no need to create it), make sure that the username (referenced in the error) assigned to the user in the target org matches the username from the source org - this way your deployment shouldn't fail.

How to remove the username(s) from my deployment package?

If you'd like to try to remove the user from your deployment package, you can download the entire deployment package, then make the change on your local device (within the XML file of affected metadata), and once this step is done you'd use the amended package as a source of a new deployment.

Alternative workaround

Use Gearset's environment variables feature to deal with the failing username(s) to either:
- Replace them with a blank,
- Or replace them with a username that's already used in the target org.

Disclaimer: This error is returned directly by Salesforce, rather than Gearset. Even so, we offer guidance based on our combined experience with the Metadata API. Where possible, we try to help guide you to fix or avoid this error. In the case that this isn't possible, we may need to direct you to Salesforce support for further clarification.
