The document “xyz.trace” could not be opened. Document Missing Template Error

[drazen-todorovic]

The command

open target/instruments/xyz.trace

Causes the following error: "The document “xyz.trace” could not be opened. Document Missing Template Error".

I am running the cargo instruments with the following command:

cargo instruments --package backend --template alloc --bin backend --release

Debug info for the release profile is enabled.

Os version: macOS Sonoma 14.0
Chip: Apple M2

Latest XCode tools installed.

I'm also getting this locally, and when I try to drop my trace into https://www.speedscope.app, it produces a similar error: Failed to load format Error: Expected key form.template.

I am not sure if it helps anyone, I also encountered this issue and figured out it was because I was killing the process before it was done. My application is a server that is long running and will stop gracefully on on Ctrl+C or SIGHUP.
I was running cargo instruments --template alloc, waiting for a while and then killing it with Ctrl+C.
Moving to cargo instruments --template alloc --time-limit 30000 solved this problem.
