Index was out of range. Must be non-negative and less than the size of the collection.

Getting the following error when generating my typescript file. This is on the latest version of nswag.

Worked fine on a previous version (can't remember which version exactly, think it was 10. something)

Somewhere in your swagger spec you have an enumeration and a default value which is (probably) not in the enumerations list... Can post this part of the spec so that I can reproduce this problem?

I think I've fixed this in NJS (see commit above) and upgraded NJS in NSwag, please test with the latest CI artifacts: https://ci.appveyor.com/project/rsuter/nswag-25x6o

Thanks for this, it has partially fixed the issue for me, i no longer get the index out of range exception now.
But i noticed some issues with default values being set now:

src\common\api.ts:6315:69
TS2339: Property '_0' does not exist on type 'typeof DiscountUsageLimitType'.

I am using string enums, but it looks like it's trying to refer to my enums as integers.

I may be wrong though.
