No config. Nothing special

Steps to reproduce

1. create minimal.yaml with the content above
2. docker run --rm -v "${PWD}:/local" openapitools/openapi-generator-cli:latest generate -o /local/out -g haskell -i /local/minimal.yaml
3. cd out/
4. stack build <-- fails

Hi @lugggas,

if you specify security schemes the generated code uses servants generalized authencitation. It currently does not support multiple schemes simultaneously (https://github.com/OpenAPITools/openapi-generator/pull/12470). An alternative solution that could work is to use wai middlewares (wai-extra and probably wai-middleware-bearer).
