Seems this is more of a backend issue than a frontend one. Currently unable to reliably reproduce this.

Recent attempts seems to result in success.

Here's my Scarb.toml file:
It seems to happen when I have a dependency in this file.

[package]
name = "mycontract"
version = "0.1.0"
edition = "2023_11"

# See more keys and their definitions at https://docs.swmansion.com/scarb/docs/reference/manifest.html

[dependencies]
starknet = "2.5.4"

[dev-dependencies]
snforge_std = { git = "https://github.com/foundry-rs/starknet-foundry", tag = "v0.22.0" }

[[target.starknet-contract]]
casm = true

[tool.voyager]
my_contract = { path = "lib.cairo" }

You're right, looking at the backend logs it seems to be the case.
Will investigate the backend implementation.
