Description

• schema-api-server
• swell-checkout

During the investigation, it turned out that some browser extensions led to the duplication of all Vault requests (not only POST /intents). Vault requests are executed using JSONP, which may not work correctly due to browser extensions.
The fix is to use the fetch instead of <script src="***" /> request.

Testing

• Added unit tests for the vaultRequest function.
