OpenAPI V3 - Cannot parse OpenAPI v3 definition file with schema containing 'additionalProperties' with boolean value

Hello,

I started to use the latest version of autorest (3.0.6187) which supports OpenApi v3. I have definition file generated from swagger using SwashBuckle library (using .net core application).

I am generating client with autorest using parameter --v3. However autorest returns following error FATAL: AutoRest.Core.Logging.CodeGenerationException: Error parsing swagger file. Error converting value False to type 'AutoRest.Modeler.Model.Schema'. Path 'components.schemas.BrandDto.additionalProperties', line 1, position 1439.

It seems that autorest does not support boolean values for additionalProperties as it is supported by OpenApi v3. Anyway if I change the additionalProperties : false to additionalProperties : {} it starts to work.

Here is the sample json used:

            }

    }
  }
}

Hi, using --use:@autorest/csharp-v3@3.0.0-dev.20200512.1 or --use:@autorest/csharp-v3@https://github.com/Azure/autorest.csharp/releases/download/3.0.0-dev.20200512.9/autorest-csharp-v3-3.0.0-dev.20200512.9.tgz (as mentioned here) did not help.

However using parameter --version=3.0.6274 helped! Thanks to bernarden

The only thing that should matter here is the core version (--version=next). Closing as this seems to have been resolved. Will publish to latest in the next few days.
