Setting config.yml in version 1.8.0 is not working

[ianhomew]

Hi devs,

avail-light --config /root/avail-light/config.yml --network goldberg --identity /root/avail-light/identity.toml

My problem is that the config file is not working. avail-light still load the old default config in v1.8.0

Here is the config.yml below which is from "avail.sh":

bootstraps=['/dns/bootnode.2.lightclient.goldberg.avail.tools/tcp/37000/p2p/12D3KooWRCgfvaLSnQfkwGehrhSNpY7i5RenWKL2ARst6ZqgdZZd','/dns/bootnode.1.lightclient.goldberg.avail.tools/tcp/37000/p2p/12D3KooWBkLsNGaD3SpMaRWtAmWVuiZg1afdNSPbtJ8M8r9ArGRT']

@ianhomew can you kindly share the logs you are referring to?

Whenever you pass the network flag, some preset config related to that network is uploaded by default. if you are willing to override those network configuration parameters, you will have to pass them separately into the config file.

I copy your config but it not working.

nano ~/avail-light/config.yml

paste your config content.

nano /etc/systemd/system/avail-light.service

Can you set this in your config

WorkingDirectory=/root

and the service file will be without the '' on config and identity

It still not working. I'm using v1.7.10. Why team don't update new rpc on source for user? RPC default can not connect.

Me too. Seems like team doesn't want users to connect to RPC. Lots of users face the same error.

[vbhattaccmu]

Hi! First of all thanks for the issue. Yes one of the RPCs on the default network list are currently not operational and hence we can use the config flag instead to start the client instead of passing the network flag.

Also I noticed that the config I shared earlier from the docs is having the seed phrase as an input which needs to be updated as follows:-

`secret_key = { seed={seed} }`

An example would be
`secret_key = { seed="111" }`

And your service file now, will look like this

[Unit]
Description=Avail Light Client
After=network.target
StartLimitIntervalSec=0
[Service]
User=root
ExecStart= /root/avail-light/target/release/avail-light  --config /root/avail-light/config.yml --identity /root/avail-light/target/release/identity.toml

You can use this config I have shared below and I could start the client with this:-

Please ensure that the file paths on the service file are consistent with the location of the binary, config and identity.toml files. Would be happy to resolve any further issues if they arise.

[vinatechpro]

It's working, isn't it? I'm not sure because there's a change of result which is not success status.

[vbhattaccmu]

You have passed the seed error stage but from the logs, it seems like your service is still not picking up the config.

You can try the following:-

1. Clean up your old avail_path artifacts and kill any existing processes using pkill -9 avail-light
2. Start the client manually from your shell to check for permission issues /root/avail-light/target/release/avail-light --config /root/avail-light/config.yml --identity /root/avail- light/target/release/identity.toml
3. I have a fresh set of RPC endpoints for you to try which you can replace on the config.yaml to make sure your client is not running into any connectivity issues. full_node_ws= ["wss://rpc-goldberg.sandbox.avail.tools:443", "wss://lc-rpc-goldberg.avail.tools:443/ws", "wss://avail2.polkadotters.com:443/ws", "wss://avail-goldberg-rpc.polka.p2p.world:443"]

Many thanks for your support, I will try it and give feedback. I have a question, if I clean up the avail-path folder will this affect my reward points calculation? Because before that I ran early and had many success reports.

[vbhattaccmu]

Nope you will have to maintain the identity.toml file to keep running with your old avail address. The avail_path simply stores artifacts from the run. I would also recommend simply running this command behind the service file curl -sL1 avail.sh | bash instead if you are performing this task for the LC challenge. This tool sets up everything for you to be able to run the LC on goldberg. For a newly set config you can follow the steps I mentioned above.

unbelievable. avail-light.service status had seed = 'aaa' but full_node_ws still connect to wss://goldberg.avail.tools:443/ws. I have no idea, why?

You will have to remove the --network flag from the command as now you are feeding a custom config. Currently the --network flag overrides the RPC URL fed from the config and replaces it with a server URL endpoint which is inactive.

It's working successfully. Thank U so much from the bottom of my heart. I have understood all of the matter.

Also please note that you are currently running the LC in client mode. Please do explore other modes and what they imply and how they operate. You can reach out to [email protected] for any queries.
