Hi,
i observed a bug in the service simulator which is the reason why my skill gets rejected over and over again (which incidentally is also very frustrating!)
1) Certification test: "[do something] ein und zwanzig" (einundzwanzig: german word for 21)
-2) Service detects some number and creates a request with the intent slot (slot type: AMAZON.NUMBER) value: "someNumber": { "name": "someNumber", "value": "20" },
3) Certification result: failed, my skill responds with the message: "Your number is 20"
The number 20 has been passed by the simulator request to my aws lambda, so my skill is working fine. The simulator, which seemingly also gets used by the certification team, is parsing a wrong number from the test utterance. This issue appear for most german numbers above 20
Best solution would be to use real numbers for testing instead of word-variant.
