Unhandled Error: There Has Been an Error Processing the Registration Request: 'ascii' Codec Can't Encode Character

Symptom

When you register a Linux system through the API, the registration returns the following error:

{
    "name": "UnprocessableEntityError",
    "message":"Unhandled error: ('There has been an error processing the registration request:', \"'ascii' codec can't encode character u'\\\–' in position 28: ordinal not in range(128)\")",
    "code": 1779
}

Cause

The sudoers file contains a Unicode character that the product cannot process. In the example, a sudo command contains an en dash (Unicode character U+2013) instead of a standard dash.

Resolution

1. Open the sudoers file:

   sudo visudo

2. Replace every en dash with a standard dash, and then save the file.

3. Register the system again.
