[BUG] Error when accessing swagger UI

[iodone]

Tapir version: *** 1.0.0 Scala version: *** 2.13.8

Describe the bug

My code:

import sttp.tapir.swagger.bundle.SwaggerInterpreter

  private lazy val endpoints = List(
    AuthEndpoint.checkTable,
    AuthEndpoint.checkPermission,
    TestEndpoint.helloWorld
  )

  private lazy val swaggerEndpoints = SwaggerInterpreter().fromEndpoints[Future](endpoints, "xxxx", "xxxx")
  lazy val route: Route =
    serverInterpreter.toRoute(swaggerEndpoints)

The following error occurs when accessing the url: 0.0.0.0:8080/docs

What is the problem?

How to reproduce?

Maybe you can provide code to reproduce the problem?

Additional information

Do you have any other dependencies in your project? Any non-standard classloader / classpath setup?

I could not reproduce this with Tapir 1.3.0. Feel free to reopen if you're still having such issues with Swagger endpoints.
