I'm trying to use AutoRest to generate C# classes from https://docs.docker.com/engine/api/v1.26/swagger.yaml

I converted it to Json using http://editor.swagger.io and the converted file is attached (renamed to txt).
swagger.txt

Code generation failed.
AutoRest.exe -Namespace Docker.DotNet.Models -Input swagger.json
error: [FATAL] Error parsing swagger file. Error reading string. Unexpected token: StartObject. Path 'default', line 19, position 15.

Can someone tell me what is wrong with it? Other tools like NSwag is able to run it perfectly.

Thank you!
