🐞 The Bug
The OpenAPI spec loader has a
discoverRoutes
method which explores an OpenAPI document and gathers information about the paths and parameters used.The list of discovered path parameters is used to install parameter-specific middleware in
src/openapi.validator.ts#installPathParams
Path parameters declared with
$ref
were not detected in thediscoverRoutes
implementation, leading to the un-coerced values being used.The Fix 🔧
By dereferencing each path parameter when building this list, we should see the same behavior for referenced path parameters and for inline path parameters.
Closes #803
