Path parameter format uuid fails

Context

Setting a path parameter of type: string and format: uuid never works. Removing the format works.

The message always returns: The value of path parameter id is invalid. Reason: String does not match format \"uuid\"

io.vertx.openapi.validation.SchemaValidationException: The value of path parameter id is invalid. Reason: String does not match format "uuid" at io.vertx.openapi.validation.SchemaValidationException.createInvalidValueParameter(SchemaValidationException.java:39) at io.vertx.openapi.validation.impl.RequestValidatorImpl.validateParameter(RequestValidatorImpl.java:132) at io.vertx.openapi.validation.impl.RequestValidatorImpl.lambda$null$2(RequestValidatorImpl.java:99) at io.vertx.core.impl.ContextImpl.lambda$executeBlocking$1(ContextImpl.java:191) at io.vertx.core.impl.ContextInternal.dispatch(ContextInternal.java:270) at io.vertx.core.impl.ContextImpl.lambda$internalExecuteBlocking$2(ContextImpl.java:210) at io.vertx.core.impl.TaskQueue.run(TaskQueue.java:76) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1144) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:642) at io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30)

Do you have a reproducer?

Hey @re-thc thanks for the report. Can you pass a sample UUID that is failing? They should all be checked against this regex https://github.com/eclipse-vertx/vertx-json-schema/blob/4.x/src/main/java/io/vertx/json/schema/impl/Format.java#L85. Im wondering if the regex is potentially wrong here. Also, if this is something you are willing to dog into I can help point you in the right direction 🙂

Thanks!

Hey @re-thc
I am not able to reproduce this at all, can you please send me a sample openapi spec that you have or let me know what you are doing?

"/uuid/{uuid}": {
      "get": {
        "summary": "Info for a specific pet",
        "operationId": "showPetByUUID",
        "tags": [
          "pets"
        ],
        "parameters": [

            "required": true,
            "description": "The uuid of the pet to retrieve",
            "schema": {
              "type": "string",
              "format": "uuid"
            }
          }
        ],

              "application/json": {
                "schema": {
                  "$ref": "#/components/schemas/Pet"
                }
              }
            }
          },
          "400": {
            "description": "Bad Request",
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "#/components/schemas/Error"
                }
              }
            }
          },
          "default": {
            "description": "unexpected error",
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "#/components/schemas/Error"
                }
              }
            }
          }
        }
      }
    }

This is what I have and I have tested against various UUIDs

createRequest(HttpMethod.GET, "/uuid/" + UUID.randomUUID())

They are all passing without any problems.
