When I tried to modify 'Description' field under link properties, I am seeing following error:

Right now I have 'column index' as 'Regular' & tried to change it to 'None'. & when I try to to this, I get the following error:

------------------------------
GT::SQL::Editor (24604): Cannot create index on 'Description' as it is a text/blob field at (eval 23) line 50.
------------------------------
Any idea on how to fix this?

Thanks.
