Error starting a node: canvas --dev --tmp

[alixeb]

1. Install dependencies with: cargo install canvas-node --git https://github.com/paritytech/canvas-node.git --force --locked. It fails without using --locked.

2. Run canvas --dev --tmp

3. Get some errors in the terminal saying it is a bug and to create an issue

Any suggestions to troubleshoot and fix?

Thanks

It fails without using --locked.

This is because we follow the Substrate master branch, so when you build without --locked it'll pull in the latest Substrate code which usually includes breaking changes. With the --locked flag it'll use the Cargo.lock file which is a "known good".

As for the error, it looks like it comes from hyper-rustls-0.21.0, not canvas-node itself. We bumped hyper-rustls in #71, can you try building with that PR (or waiting until it hits master) to see if your issue gets resolved?

If it doesn't, I'd recommend opening an issue in the hyper-rustls repo.
