Generation Details

Steps to reproduce

Running the above results in a OOM heap space exception. I don't see any additional logging with the -Dlog.level=debug

As an additional note, commenting out the Search method from BulkDownloadController makes the following changes and allows for the swagger generation to complete.

diff swagger_bad.json swagger_good.json

the above is the only difference in the spec file.

Why is c# in the description when the config says typescript?

[PeterVaccaITR]

Apologies. The API source code that produces the spec is C#, the code we are generating with openapi is typescript.
