While trying to send the PO with an incorrect request (incorrect order properties, the PO request ends with an error status, but the "Response XML" tab remains blank.

Repro steps: 

1. Configure an external catalog
2. Configure incorrect order properties (Setup ‘Tracesend’ = True’ in external configuration)
3. Create a PR and add lines using the External catalog button
4. Convert the PR into a PO
5. Confirm the PO

Result: The PO request ends with an error, but error messages are not in detail and pin pointing which step exactly missing or need to be corrected.

For example -

When PO failed, response XML updated with below detail log -

Check if headers are required :

Content type : false

Checking supplier URL

Supplier URL : XXXXX

The remote server returned an error: (500) Internal Server Error.

When PO sent successfully/passed , response XML updated with below detail log -

Check if headers are required :

Content type : false

Checking supplier URL

Supplier URL : XXXXX

Get the text of the response message.

Response Code : 200

If the response code is 200 the vendor likely received the document.

Expectation - User expecting to get error log updated with detail explanation some thing like how 'Response code:200' updated with detail when the PO submitted successfully.
