The report reproduces the error in the express-ts-mock example at examples/express-ts-mock/index.ts while using a YAML file, and the stack trace points to fast-json-stable-stringify. Start by comparing the YAML mock input with the example's request flow and inspect the comments for further diagnosis. Done means identifying and documenting or fixing the cause of the circular value during serialization; the issue has had no recent activity.

I'm using example "express-ts-mock" (https://github.com/anttiviljami/openapi-backend/blob/master/examples/express-ts-mock/index.ts)

but this is the result...
