add request-id from header to error body

[oliverdding]

I want to retrive request-id header from request and set it to the error body, but after browsing the code, it's not possible without modifying the source code. Can anyone give me an advice?

You can probably use a router-specific middleware for this, or a transformer. Example: https://go.dev/play/p/oJ01FZwBzdj
