I expect that on the client side, i would just render the message, not the whole error stack

@random plume try error.data.message, that should be what you pass in

#

see https://docs.convex.dev/functions/error-handling/application-errors

hey @burnt epoch i just figured that it works if i do it like this

#

kinda hoping that convex would automatically handle the type of the thrown error

#

i probably expecting to high lol

Say more, automatically handle how?

#

@random plume do you want to set a global handler and always toast or something?

#

im saying i dont want to add that ConvexErr type on the onError callback

#

or maybe im such a noob on error handling haha

Ah got it, actually careful since there are other errors you could get here too! ConvexErrors are the only ones that will have messages attached, but other built-in errors can throw here too and they're just normal errors. In dev they'll have stack traces and messages and all but in prod they're more like Error("server error")

#

so as not to leak information from the backend
