Schema claims AWS::Serverless::Api Models object is 'key : string' map

[lucianomm]

While on SAM docs it says the object should be of type Map, as shown here:
https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/sam-resource-api.html#sam-api-models
The actual schema expects a pattern of 'key : string'

"Models": {
"additionalProperties": true,
"patternProperties": {
"^[a-zA-Z0-9]+$": {
"type": "string"
}
},
"type": "object"
},

The schema I found with the incorrect models object is:
