  TypeError: translate() takes exactly one argument (2 given)

Environment

• CB Response Server: 6.2.2 and higher
• Linux: All Supported Versions

Cause

The Python function, translate, no longer supports multiple arguments.

Resolution

• For more reliable results, use the Python replace method instead of translate. 
• If a different method is failing, review Python notes for the method in the new version.
