RangeError: Maximum call stack size exceeded in case of complex nested models

What version of the library are you using? Is it the latest version? The latest released version is
2.9.0

Bug report
In case of big request json spec, I get following in console after trying to expand the operation in swagger-ui and the section of operation shows endless spinner. After refreshing we see the operation details.
If request model is not big but only response response is big, it works fine so I am inferring that it might be related to the size of request model or the combined size, not sure.

This is probably a bug in Swagger-ui. Its not the size as much as how its handling recursive models.

[gaurav517]

I see. The models with issues indeed have layers of recursion. Yea, seems javascript is falling into some endless recursion. Should we open it in Swagger-ui repo? Please let me know after your initial analysis. Thanks.

[dilipkrish]

That was the analysis :)

[gaurav517]

Created an issue in swagger-ui repo.
swagger-api/swagger-ui#4637

[dilipkrish]

Would be useful to provide them the model IMO, to use as a test.

[gaurav517]

yea.. will do that. will have to scramble some data. tomorrow! bit late here now.

@ALL - Any updates on this issue ? How we can solve this ?

[dilipkrish]

It seems to be a closed issue in swagger-ui

Nope, it seems not fixed. I am still getting the same error. Swagger version
