Error Approving Email - Token Key Not Found

[#1]

Issue

You're receiving an error that states 'Not Allowed - Error approving <asset-name> - {{token-name}} : Token key not found' when trying to approve an email asset.

Solution

1. Check that token syntax is correctly inserted with no missing left or right 'curly' brackets '{{' '}}'
2. Check that the field name of the token does not have any incorrect spelling (e.g. Email Address)
3. If the token syntax is correct and the field name of the token is spelled correctly, it is possible that the field name of the token contains a Unicode non-breaking space (e.g. between 'Email' and 'Address'). This would have been inserted if it was copied across from a platform that was encoded with Unicode (e.g. Microsoft Word) - To rectify this, delete the space in the token and re-insert it with a normal space using the spacebar on the keyboard. Once this is corrected, the email approval should work.
