ROOT CAUSE:

When you encounter the above error,every time when indexing is running in place , it will look for the properties or dimensions defined here if it is not available then it will throw the merge error. 

IDENTIFICATION:

Delete the particular property from the DB , so not a single value is found then this error will occur.

SOLUTION:

 Remove the Value from the indexconfig and set the indexing config again, then you are set 
For more information on setting the config see my earlier posts .
