How to Reproduce

I tried asyncapi/generator:1.0.0-rc.10 container, but it reproduce on asyncapi/generator:0.53.1 also.

Inside the container, I call
node cli.js -o /data/public /data/web.yml @asyncapi/html-template --force-write

Expected behavior

Should work and generate HTML.

Welcome to AsyncAPI. Thanks a lot for reporting your first issue.

Keep in mind there are also other channels you can use to interact with AsyncAPI community. For more details check out this issue.

@Ellocsys you mean you're getting error with latest generator too or only older? circularProps is a new prop added to schema b the parser, in generator rc.10, maybe since rc.8

[Ellocsys]

@derberg latest (tried on asyncapi/generator:1.0.0-rc.10) and older (tried on asyncapi/generator:0.53.1 and asyncapi/generator:0.50.0).

[derberg]

@Ellocsys could you share your schema file?

[derberg]

@Ellocsys the circularProps() operates on the properties of the object. If there is no x-parser-circular-props propert added to the object by the parser, then it just returns undefines. So I just need to see your schemas to see what is wrong with them, or what is wrong with my assumption 😄

I have a similar problem with circularProps.

[derberg]

@Igor-lkm could you please first upgrade to latest generator v1.0.0-rc.11? The previous versions of generator did not use latest parser that adds those circularProps

[Igor-lkm]

@derberg works! thank you

[Ellocsys]

@derberg it works for me too! Thank you for help
