Is there a file size limit? the swagger is 670K characters.

There shouldn't be a size limit but there could be a hidden BOM handling issue. Is that swagger file something you can edit? Does it have a BOM? Does it work if you remove the BOM? Worth mentioning that Radzen currently supports only Swagger 2.0.

Thanks for your reply. Yeah it's a local file. Just text supposed to be UTF-8. How would I check for BOM?

Is there a way to select only a subset of paths from swagger?

No, there isn't. We better check that swagger file of yours. Can you either attach it here or send it over at [info@radzen.com](mailto:info@radzen.com)?
