Expected Behavior

CanFulfillIntentRequest request structures should be supported.

Current Behavior

If a request of type CanFulfillIntentRequest is received, it fails validation during Request deserialization.

Context

Notice I'm not asking for canFulfill "support" within the SDK (helper functions, etc), just allowing the request canFulfill structure to pass deserialization validation. Without it, it appears we'll have to resort to hacking the SDK itself.

I agree this would be a great feature. In the meantime, I've been using a workaround with Chalice. Set up your lambda handler to a pure lambda function (docs here). Then inside this pure lambda function you can use

try:
    sb.lambda_handler()(event, context)
except  SerializationException:
    # respond to CanFulfillIntentRequest

so that you can handle CanFulfillIntentRequests yourself.

Hey @timothyaaron , thanks for the feature request. Will look into supporting the CanFulfillIntentRequest support.

@mhole44 , that's a nice little workaround. Thanks for posting around.

If it's accepted, I'll follow it up with a PR to allow CanFulfillIntentRequest to use the is_intent_name helper.

Hey @timothyaaron , thanks for the PR. Updated the PR

If anyone else is interested, I've forked and created a branch to handle CanFulfillIntentRequest. https://github.com/timothyaaron/alexa-apis-for-python/commits/can.fulfill

Hey @timothyaaron , @mhole44 , sorry that this feature took some time to come over to Python. But it is out now. Please update your models and SDK packages to the latest to get this over. Excited to see what the community builds using these.

PS: The feature is still under beta, so it might change during the GA release. So please take that into consideration.

Is it already released? by updating the SDK? Thanks!

[nikhilym]

Hey @cnpants, yes, this feature has been released. Please update your SDK package to the latest version to use it.
