Lost on this Axum error... any thoughts?
Lost on this Axum error... any thoughts?
Not sure what happened exactly... it was working fine and I didn't change anything in this file. It has to be related to something I did recently:
- Ran a migration adding a unique constraint on a table
- Generated two new entities of a couple very basic tables.
The handler I'm using isn't even using the new tables, so I don't know why this randomly broke. Anyone have any ideas? Or even some guidance on how to decipher that obscure error would be helpful.
You're viewing a single thread.
Have you tried using the
#[debug_handler]macro onget_all_armies? Without that macro handler errors don't tell you much more than "something isn't right".Generally this kind of error indicates some type in the handler signature doesn't implement a necessary trait. Maybe you accidentally lost an automatically-derived trait like
Send + Sync? The macro is the easiest way to check.Oh man, I didn't know debug_handler existed. Sure enough I had a missing derived attribute... not sure how but Serde serialize and deserialize were missing, so when I was trying to return Ok(Json(army)) it was failing. Thanks so much!
You're welcome!
