Steps

1. Run command
2. See panic

Possible Solution(s)

Not running with --offline doesn't make the error occur.

Notes

Running cargo clean doesn't fix the issue

Maybe the Cargo.toml is also interesting:

[package]

version = "0.1.0"
edition = "2021"
authors = ["Marcel Müller <neikos@neikos.email>"]

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[workspace]
members = ["mqtt-format"]

[[bin]]
name = "cloudmqtt-client"
required-features = ["bin"]

[features]
bin = ["clap", "tokio/rt-multi-thread", "tokio/macros"]

bytes = "1.1.0"

Thanks for reporting this!

A fix is posted but in the mean time, cargo --offline add nom-supreme should work

[TheNeikos]

Great! Thanks for the quick fix
