fatal runtime error: failed to initiate panic, error 5

[dolcalmi]

ClientShim initialization is failing with "fatal runtime error: failed to initiate panic, error 5" (command: node ./demo/ecdsa-party2.js)

I debug it and the line that throws the fatal runtime error is https://github.com/KZen-networks/thresh-sig-js/blob/master/native/src/party2/ecdsa.rs#L99 ( I tested directly downloading the repo and with terra-thresh-wallet repo)

My Environment:

• OS: Ubuntu 18.04.5 LTS
• Node version: v10.19.0
• Rust version: rustc 1.38.0-nightly (0b680cfce 2019-07-09)

Other considerations:

• The server is running successfully (command: node ./demo/party1.js)
• I tested updating gotham-city to v0.1.3 but still got the same error

Hey, the client implicitly expects the server to be listening on HTTP://localhost:8000.
Could you verify the server is indeed listening on this port?

[dolcalmi]

yes, is running in that port. I didn't change default settings.

Also, not sure if is related with server connection because is just the initialization of the object (also checked class implementation and does not seems to be doing nothing weird https://github.com/KZen-networks/gotham-city/blob/master/gotham-client/src/lib.rs#L55)

ps: Also I did a test only with gotham and is working (is not a library test but just want to be sure that my OS was not blocking the port or the process)

[dolcalmi]

I just did another test cloning gotham and adding some println (apologies I dont know rust) and the line that throws the error is https://github.com/KZen-networks/gotham-city/blob/master/gotham-client/src/lib.rs#L56

this is my fork https://github.com/dolcalmi/gotham-city/blob/master/gotham-client/src/lib.rs#L57 ( I only got the first message "gotham ClientShim before client creation http://localhost:8000" )

This may also happen if the server does not have the same share id as being queried by the client.
I'd recommend deleting the client's DB (e.g. in terra-thresh-wallet search for the directory client_db, delete it if you didn't generate any important address) and trying again ...

[dolcalmi]

the last was tested in this library, also no connection was done at that point ( is just an initialization without url or connection to the server let client = reqwest::Client::new();)

[oleiba]

I tested on a clean Ubuntu 18.04.5 LTS machine with the exact configuration you detailed, and the demo went through.
If you like, we can schedule an online debugging of the issue.

"One eternity later" and just for future reference.

the error is the same as shown here nodejs/help#2376

and related with the comment in https://docs.rs/reqwest/0.10.7/reqwest/struct.Client.html#method.new

This method panics if native TLS backend cannot be created or initialized. Use Client::builder() if you wish to handle the failure as an Error instead of panicking.

really not sure why is not linking with the OS TLS lib but I had to compile the native lib with the next command (package.json):

"build-rust": "OPENSSL_STATIC=yes OPENSSL_LIB_DIR=<openssl path> neon build -r",

you can get openssl path with:

> openssl version -d

Hope it helps

Wow. Thanks for the thorough analysis and reaching back with this info!
