There was a problem hiding this comment.
But are we sure using the core schema is not going to break other stuff? I.e: is "No" going to be encoded correctly (read: quoted), or is it going to be encoded YAML-1.2-style (which in Yaml 1.1 is an alias for false?
There was a problem hiding this comment.
Good point! I added a test confirming that No is deserialized correctly (as "No", not false).
Let me know if you want to see some more tests of some edge-cases in the YAML handling!
Currently, we are using the `yaml-1.1` schema when de-serializing YAML documents, Unfortunately, this has the side effect of treating unquoted parts of the template like '2010-09-09' as Date objects, instead of just simple strings. This has been noted by a customer using the cloudformation-include module, but I assume a very similar problem exists for other places we parse YAML, like cloudformation-diff. Switch to the `core` schema from `yaml-1.1`, where those are treated as strings, instead of dates. Fixes aws#13709
