How to Extend InternalServerError for Enhanced Logging in Effect Typescript Library

I have defined an error:

class InternalServerError extends Schema.TaggedError<InternalServerError>()('InternalServerError ', {}) {}

class InternalServerError extends Schema.TaggedError<InternalServerError>()('InternalServerError ', {}) {}

and I am using this successfully in the handler.
My question is how can I extend this class so it can be logged in the logger.
I'm using

HttpApiBuilder.serve(HttpMiddleware.logger)

HttpApiBuilder.serve(HttpMiddleware.logger)

I would like something to show more in the logs than just the bare info:

[18:05:56.093] INFO (#19) http.span.1=52ms: Sent HTTP response
  http.status: 500
  http.method: PUT
  http.url: /household

[18:05:56.093] INFO (#19) http.span.1=52ms: Sent HTTP response
  http.status: 500
  http.method: PUT
  http.url: /household

it only shows this, but I'd like to include the message and stacktrace. I found out that if I do the fail like this in the body of

.handle

.handle

Effect.failCause(Cause.fail("message"))

Effect.failCause(Cause.fail("message"))

then it will display the error message:

[18:07:37.678] INFO (#19) http.span.1=50ms:
  Error: message
  http.status: 500
  http.method: PUT
  http.url: /household

[18:07:37.678] INFO (#19) http.span.1=50ms:
  Error: message
  http.status: 500
  http.method: PUT
  http.url: /household

I'd like to be able to somehow enrich the class of

InternalServerError

InternalServerError

so I can add more info that would then be logged. How can I do this?
