Failed to run examples

[flyq]

Here is my step:

1. Git clone this repository, and build the examples
2. Copy the Rocket.toml to ./target/release/examples
3. Run the demo: ./demo/run.sh

Here is error logs:

$ ./demo/run.sh

I modify the run.sh to show the verbose backtrace.

I think it's coursed by the params.json.

I copy the params.json to ./target/release/examples, and modified it:

case 0:

params.json:

{"parties":"", "threshold":""}

error:

$ ./gg18_sign_client http://127.0.0.1:8001 keys1.store "KZen Networks"
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: ParseIntError { kind: Empty }', src/libcore/result.rs:1051:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.

case 1:

params.json:

{"parties":3, "threshold":1}

error:

./gg18_sign_client http://127.0.0.1:8001 keys1.store "KZen Networks"
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error("invalid type: integer `3`, expected a string", line: 1, column: 12)', src/libcore/result.rs:1051:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.

case 2:

params.json:

{"parties":"3", "threshold":"1"}

log:
when I only run the keys1:

$ ./gg18_sign_client http://127.0.0.1:8001 keys1.store "KZen Networks"
number: 1, uuid: "99e33651-1ea3-49e0-abf5-71269e0a1bab"

when I run the keys2: error:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error("invalid type: map, expected BigInt", line: 1, column: 77)', src/libcore/result.rs:1051:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.

The params.json is ignored by .gitignore, anyone can supply the current one?

[omershlo]

Hi, I am looking into it. We recently introduced some changes to master branch that probably caused the example to fail. You can try earlier tags meanwhile.

[flyq]

OK, I'll try it. Thx

[omershlo]

Fixed now
