Lambda Function test returns error re: session applicationId

[pullejo]

I'm guessing I don't have the correct application Id somewhere and I'm having trouble figuring out where.

When I run the test:

{
"session": {
"new": true,
"sessionId": "session1234",
"attributes": {},
"user": {
"userId": null
},
"application": {
"applicationId": " amzn1.ask.skill.9c3e5fcc-fea0-4036-bec3-3c40edd2e000"
}
},
"version": "1.0",
"request": {
"intent": {
"slots": {
"Preset": {
"name": "Preset",
"value": "test"
}
},
"name": "PlayPresetIntent"
},
"type": "IntentRequest",
"requestId": "request5678"
}
}

I get the result:

Where do I have my application ID messed up?

You shouldn't publicly post your app-id.

My guess is that you didn't properly link your skill to your lambda app.
Try using the test tool in the skill.
