How can we help?

I would really like a way to disable parameter and request body validation in swagger-ui. We are using swagger purely as documentation, and as a way to demo our rest api. We have our own validation engine implemented in our backend, which we are unable to test because swagger-ui parameter validation will not send a request where a parameter is f.ex. less than what is specificed via a "minimum" constraint, see part of the schema definition below:

"VedvarendeEnergiOplysningerDTO": {
    "properties": {
		"maksAntalVindmoeller": {
			"type": "integer",
			"format": "int32",
			"description": "Gemmes kun hvis specifik anvendelse Vindmølleanlæg (8111) er angivet.",
			"minimum": 0,
			"maximum": 9999999
		}
    },
    "type": "object"
}

We can not test that this minimum constraint works in our backend, because swagger-ui refuses to send the request in the first place. But it refuses to send the request without any feedback to the user. So now I'm wondering, is there a way to disable this validation?

I checked the source code, and in execute.jsx the onClick callback for the Execute button calls handleValidateParameters() and handleValidateRequestBody(), that I would like it to skip.

Start in execute.jsx, where the Execute button calls handleValidateParameters() and handleValidateRequestBody(); trace how those callbacks prevent requests from being sent. The work is complete when Swagger UI provides a way to bypass parameter and request-body validation so requests violating constraints can still be sent.
