You cannot have a multiline plain scalar, such as your include:false transitions be the key to a mapping, that is why you get the mapping values not allowed in this context error.
Either you forgot that you have to have a space after the value indicator (:), and you meant to do:
include: false
transitions:
or you need to quote your multi-line scalar:
'include:false
transitions':
or you need to put that plain scalar on one line:
include:false transitions:
