Fuzzing - POST endpoint with payload - Amount as Float data type about cats HOT 8 CLOSED

Hi @josip1001. Is everything ok with 7.2.1?

from cats.

Hi @josip1001. Thank you for raising this. I'm struggling though to reproduce it. If I run the above command using the provided OpenAPI contract, I get payloads like this:

{
  "amount": "7.50",
  "petUid": "eqnpkbeh",
  "name": "7qEow",
  "hashtag": "rdTbbpCNB"
}

Which version of CATS are you using?

from cats.

Hi, I am using latest version(7.2.0) and I have still got same error :

{
"responseCode": 400,
"httpMethod": "POST",
"jsonBody": {
"status": "error",
"error": {
"message": "The type of the "amount" attribute for class "App" must be one of "float" ("string" given).",
"code": "validation_error",
"context": [],
"reason": "UNKNOWN"
}
},
"responseTimeInMs": "10373",
"numberOfWordsInResponse": "16",
"numberOfLinesInResponse": "1",
"contentLengthInBytes": "289"
}

====================
payload:
{
"amount": "3,48",
"petUid": "67DuR9XimWncU8",
"name": "PfGe5C5YTXzY",
"hashtag": "2v1fspX"
}

This seems like a misalignment between the locale of the server and the locale of your machine. The server expects data in locale en_us most probably so the amount must be something like: 5.6. Notice the . instead of , like in your example. In order to pass the locale to the app just do:

> java -Duser.language=en -jar cats-uber.jar --contract=c:\Work\pet\pet1.json --server=https://process.example.com/ --fuzzers=HappyFuzzer

when i was using Param " -Duser.language=en" value of amount contains "." instead of "," but amount is still sending with quotation marks ("") and i have still got response:

{
"responseCode": 400,
"httpMethod": "POST",
"jsonBody": {
"status": "error",
"error": {
"message": "The type of the "amount" attribute for class "App" must be one of "float" ("string" given).",
"code": "validation_error",
"context": [],
"reason": "UNKNOWN"
}
},
"responseTimeInMs": "10522",
"numberOfWordsInResponse": "16",
"numberOfLinesInResponse": "1",
"contentLengthInBytes": "289"
}

=======================
Payload:
{
"amount": "4.11",
"petUid": "2UqgiSmlmbOe",
"name": "LkaBFjtEgdc",
"hashtag": "2r20kA3"
}

Usually frameworks in most of the languages will automatically convert string to appropriate types from the backed object. I've changed though to leave every numeric field as Number. 7628067

Will be available in the next release.
