TRPCError that has TRPCError as cause

Having some troubles with error handling, specifically, my errors are double-wrapped in a TRPCError. What I'm doing is basically having a mutation that does:

something: t.procedure
  .input(mySchema)
  .mutation() => Promise.reject(new Error('oh no'))),

something: t.procedure
  .input(mySchema)
  .mutation() => Promise.reject(new Error('oh no'))),

and then, the onError handler has:

onError({ error }) {
  console.log('onError', error.name, error.cause.name)
},

onError({ error }) {
  console.log('onError', error.name, error.cause.name)
},

which logs: onError TRPCError TRPCError. If I then go further with error.cause.cause.name, I can see my error. I already tried to reproduce this in isolation, but in a sandbox, I get: onError TRPCError Error, which is what I would expect. Just wanted to know if anyone has seen something similar; Not sure how this can happen ... thanks

yeah that fixes it. Thank you so much 🙏 I'm not quite sure why I couldn't reproduce it in isolation though
