Enum string value "YES" becomes "true"

[piebur]

Version

• vert.x core:3.7.0
• vert.x web:3.7.0

Context

I encountered an exception which looks suspicious while utilizing the enum property with the value "YES"

Do you have a reproducer?

• Link to github project/gist

Steps to reproduce

1. Clone the OpenAPI sample https://github.com/vertx-howtos/web-and-openapi-howto
2. Add the following property into components:schemas:Pet:properties:

isMale:
  type: string
  enum:
  - YES
  - MAYBE
  - NEVER

3. Start the server and execute curl commands:

curl -X POST -H "Content-type: application/json" --data "{\"id\":4,\"name\":\"Steve\",\"isMale\":\"YES\"}" http://localhost:8080/pets

-> {"code":400,"message":"$.isMale: does not have a value in the enumeration [true, MAYBE, NEVER]"}

Extra

Work around: Add " around the enum value "YES", see below

isMale:
  type: string
  enum:
  - "YES"
  - MAYBE
  - NEVER

curl -X POST -H "Content-type: application/json" --data "{\"id\":4,\"name\":\"Steve\",\"isMale\":\"YES\"}" http://localhost:8080/pets

-> OK

curl -X POST -H "Content-type: application/json" --data "{\"id\":4,\"name\":\"Steve\",\"isMale\":\"true\"}" http://localhost:8080/pets

-> {"code":400,"message":"$.isMale: does not have a value in the enumeration [YES, MAYBE, NEVER]"}

This sounds strange, can you open an issue here please? https://github.com/networknt/json-schema-validator

Why, the problem is connected to the conversion from yaml to the json schema within io.swagger.v3.parser.OpenAPIV3Parser. I will instead create a bug in [https://github.com/swagger-api/swagger-parser/issues]swagger-api/swagger-parser#1205

Thank you, I wasn't aware of this :)

This is solved in vertx-web-openapi, because we don't use swagger-parser anymore. I'm going to close it, reopen if you need it
