Issue: When a token-map verb is used in a project that contains the src attribute, the project does not work as expected when you try to edit the mapping from Designer. This issue is observed because the src attribute is no longer supported.
Workaround: To work around this issue, perform the following steps:
Log in to Designer.
Navigate to the policy containing the token-map verb.
Navigate to the XML Source tab.
Modify all the occurrences of src attribute to source manually.
Save the policy.
Deploy the changes.
