Cause: By default, due to security reasons, Workday rejects all requests coming from a non secured client (HTTP). If the Workday plugin application is configured to use a HTTP client, the error will be thrown at runtime and the application will fail to start.

To resolve this issue, configure the client to be secured (HTTPS). Perform the following steps to configure your client to use HTTPS instead of HTTP.

- Configure a  SSL client connection shared resource by importing the server side certificates in a JKS file.
- Go to HttpClientResource shared resource configuration.
- In the Security section, there is an option called "confidentiality".
- Check the confidentiality check box and upon doing that you will see an option which asks for an SSL client configuration.
- In the SSL client configuration, select the SSL client connection shared resource which you have configured in the first step.

Once the steps above are performed the client will be able to send request to the Workday server and receive a valid response.
