Not a biggie but in the example wallboard definition example shown in the blog there is a space between the colon and the yyyyyyyyy for the Contacts_Handled line which results in a 'mapping values are not allowed here' as the space indicates that it is (incorrectly) a key:value pair.

Reference: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx: yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy:CONTACTS_HANDLED
Removing the space to make it looks like xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy recolves the issue :)
