[SOLVED] Bare metal validator can't start: panic: runtime error: slice bounds out of range [:4] with capacity 0

Hi,

I’m trying to light-up a bare metal validator but get

panic: runtime error: slice bounds out of range [:4] with capacity 0

I’m driving the app with systemd

EnvironmentFile=/etc/systemd/system/incognito.env
ExecStart=/bin/bash -c "cd ~ && env | sort && ( cd ./incognito-chain && git log -1 ) && exec ./incognito-chain/incognito --configfile=.incognito/config.conf"

Here’s the log with some redacted info

The only edit I made to the virgin incognito.conf file was to the RPC user credentials.
Can any one offer any suggestions as to what’s going wrong? @khanhj?

Hi @3ncrypt3d,

Make sure that you have the sample-config.conf and keylist.json in same folder with the incognito binary. Copy the keylist-mainnet.json to keylist.json (the default keylist.json is for testnet)

Thanks for the quick reply. I still have the same problem, though. :frowning:

incognito-chain]$ ls -lh incognito keylist.json sample-config.conf
-rwxrwxr-x. 1 incognito incognito  50M Jun 28 10:46 incognito
-rw-rw-r--. 1 incognito incognito 111K Jul  6 08:00 keylist.json
-rw-rw-r--. 1 incognito incognito  11K Apr 19 18:29 sample-config.conf
incognito-chain]$ diff keylist-mainnet.json keylist.json 
incognito-chain]$ 

Any other ideas?

I have no experience with this at all, but you define configfile as config.conf while it is listed as sample_config.conf in your listing.

If that is not the error maybe the missing slash in your configfile definition is.

@Jamie the sample-config.conf contain default parameters if user does not include them in the command used to run incognito binary (see more below)

@3ncrypt3d, I suggest that you try this command first, to see if there is any error

[email protected]:~/jenkins/jenkins/workspace/BenchMark/BM_build_chain/inc_bin$ ls
CJN.log  incognito  keylist.json  sample-config.conf  data  logs               

[email protected]:~/jenkins/jenkins/workspace/BenchMark/BM_build_chain/inc_bin$ ./incognito --discoverpeersaddress "mainnet-bootnode.incognito.org:9330" --miningkey "your_validator_key" --testnet false --nodemode "auto" --datadir "data/CJN" --listen "0.0.0.0:9465" --externaladdress "0.0.0.0:9465" --norpcauth --rpclisten "0.0.0.0:9365" 2>&1 | tee CJN.log

then try with systemd later

Success! Thank-you, @khanhj!
