Errors when you debug against a Tier 1 Retail Server virtual machine in an e-commerce development environment

This article provides a resolution for an issue where you might receive an error when you debug against a Tier 1 Retail Server virtual machine (VM) in an e-commerce development environment in Microsoft Dynamics 365 Commerce.

Introduction

Microsoft Dynamics 365 Commerce Tier 1 environments are typically deployed for Commerce runtime (CRT) and point of sale (POS) extension development. They are standalone environments. Because of the software as a service (SaaS) nature of the architecture, they don't include e-commerce components.

In some scenarios, you might need to test calls to extensions in a Tier 1 environment so that you can debug extensions from e-commerce components. For general instructions, see Debug against a Tier 1 Commerce development environment.

Symptoms

When you debug against a Tier 1 environment, because the site is now calling a different Retail Server, cross-server calls might cause various errors that are related to the content security policy.

The following screenshot shows an example of an error that might occur when a variant is selected on a product details page.

Unhandled Rejection (ActionError): Error

The following screenshot shows an example of a similar error in a browser's debugger tools (F12 Developer Tools). The error message mentions a violation of the content security policy directive.

Resolution

To solve this issue, disable the content security policy (CSP) for the site in Dynamics 365 Commerce site builder.

1. Select the site that you're working on.
2. Select Settings > Extensions.
3. On the Content security policy tab, select Disable content security policy.
4. Select Save and publish.
