[Bug] Error: cannot find a valid VDF proof in files to determine next proof's parameters. Exiting.

[ghost]

I'm attempting to use tower, supplying a config file path and private key.

Proof 0 has been mined and exists within account/test/vdf_proofs_{account_address}/proof_0.json

My config file is located at account/test/libra.yaml and specifies node_home: account/test

libra tower -c account/test/libra.yaml -t {account_private_key} start
Error: cannot find a valid VDF proof in files to determine next proof's parameters. Exiting.

Libra: 6.9.3 (release) OS: Ubuntu 22.04.3 LTS

For debug purposes here's example steps to reproduce:

libra wallet keygen -o account/test

0L Account Address: ........................... ef3cbb0515a3cf3f8921cdff046ea464cbb5384d8b5bdfafdde888f3a60cc0fc

Authentication Key (for key rotation): ........................... ef3cbb0515a3cf3f8921cdff046ea464cbb5384d8b5bdfafdde888f3a60cc0fc

0L mnemonic: ........................... sustain clock merge control diesel either motion audit verify law wrap exist slush aerobic wild task canal unfair true quote jump arrow unknown jewel

WRITE THIS DOWN NOW. This is the last time you will see this mnemonic. It is not saved anywhere. Nobody can help you if you lose it.

Solved: insufficient gas to submit genesis proof

Sorry for the delay on this @siliconbits. Was going to take a look tonight. Glad you got it working. It was be awesome if you wanted to create your first addressing the issue. Perhaps we could add better error logging to identify as well.

Seems this isn't actually solved. My guess is when submitting proofs with tower CLI (whether genesis or otherwise) the custom config file path is ignored.

Bit of a muck-around but I used another desktop to run carpe, imported a private key (generated with libra keygen CLI on my server). This was to confirm whether the genesis proof mined with carpe GUI and tower CLI were the same - they were.

In the example debug above I had not onboarded the account. So I onboarded this new account (sent 1 coin) and attempted to submit the genesis proof (via carpe backlog). This resulted in an error about insufficient gas, I sent another 10 coins to the address and then carpe backlog was successful - although it only used 0.2 coins, so unsure why the 1 balance wasn't sufficient originally?

Next, instead of mining proof # 1 with carpe on my desktop I attempted with tower CLI on my server, this worked - I no longer got the original error and saw Mining VDF Proof # 1 instead.

I had thought success, the issue was seemingly not onboarding/insufficient gas for the genesis proof (and just some lacking helpful error notices lol).

However I came back to see the following (similar) loop:

libra tower -c account/test2/libra.yaml -t XXX start

Mining VDF Proof # 1 difficulty: 120000198, security: 512 Delay: 1759 seconds Proof mined: proof_1.json created.

Mining VDF Proof # 1 difficulty: 120000198, security: 512 [00:06:33] living is waiting ···

Additionally, if I attempt backlog:

libra tower -c account/test2/libra.yaml -t XXX backlog

backlog Error: cannot find a valid VDF proof in files to determine next proof's parameters. Exiting.

@0xzoz not sure if you noticed I reopened this issue last week, sorry to ping.

Ahh I feel stupid, absolute paths are expected in libra.yaml

node_home: /home/user/account/test

Closing this one for good now 🤣
