Swagger Parser Issues

[kleozzy]

I am always getting this error on runwhich i assume it has something to do with outdated parser?
Can you fix this?

Thanks for reaching out.
Could you please provide the yaml file you're using?

Thanks

Getting the same error. How did fix this?

[HeyThisHaku]

I got same error, but I was fix with this converter: https://editor.swagger.io/

Import ur swagger.json or yaml .json
after u import, try to export to yaml
after that, check your yaml file make sure first line is:

'swagger: [version]' because my problem the first line is not swagger but 'openfile:[version]'

[AnjiB]

I am getting the same issue even after I added the first line as swagger: 3.0.1

[thenorthernpole]

@AnjiB and all, the parser currently supports only Swagger 2.

[sertal70]

@thenorthernpole Maybe it could be worth spending 2 mins to add this valuable information in the README, just to help people to avoid wasting time to download, compile and run the tool on an unsupported OpenAPI specification.
