grin-wallet to node communication error because of wrongly created paths in grin-wallet.toml when using the Top Level Directory option.

[Anynomouss]

Running latest node (5.4.0. alpha) and wallet (5.4.0 alpha1). I setup a wallet for both testnet or mainnet, results when running 'info' command.

grin-wallet.exe -t wallet1/ info

See log below, results are the same for testnet and mainnet wallets. I always had issues with grin node and wallet on Windows although this is on a new clean machine. I will test if it also happens on Linux.

Beware phishing attempt above, deleted and reported

[martinthonon]

Can you provide the build steps so we can try to get the logs too?

[Anynomouss]

This is not a specific build, just the normal Windows release.

Just to be certain I retried any combination of local builds of grin node and grin-wallet and created a new wallet directory to be certain there was no form of corruption.
All results with the local wallet build and node build are exactly the same as initially reported.

[Anynomouss]

Ok, just noticed I did something stupid, I had Grin++ running in the back and it interferes with the IP binding.

2P server failed with erorr: Connection(Os { code: 10048, kind: AddrInUse, message: "Only one usage of each socket address (protocol/network address/port) is normally permitted." })

Still getting some errors, but at least a balance is shown. Will restart my machine to start clean from there

[Anynomouss]

Ok, this after making sure I am not running multiple instances or Grin++ which interfers since it uses the same IP and ports and grin node. Still getting errors and failing to verify against the chain:

When I look at node log, there is nothing much interesting there, the wallet log basically repeats the errors it reported back via the TUI:

[martinthonon]

Does your node is running and up to date ?

[Anynomouss]

Yes, the node is fully synced and running (status is running). At moment I am using both wallet and node software build specifically on/for my machine. Everything is clean, no changes to any of the default settings, antivirus turned of to also rule out that option,

[Anynomouss]

Ok, I did run it again setting log level to "Trace" for both node and wallet, perhaps the output is useful for you.
Note that the wallet directory says contract branch, but it just the normal main wallet and grin node I am testing so ignore that.

Open grin-wallet.toml file and correct the paths to node's API secrets:

[martinthonon]

Did the http server started in log section of your grin-node ?

You should see something like this :

20250114 16:28:06.958 WARN grin::cmd::server - Starting GRIN in UI mode...

20250114 16:28:44.066 WARN grin_api::handlers - Starting HTTP Node APIs server at 127.0.0.1:3413.

20250114 16:28:44.066 WARN grin_servers::grin::server - Grin server started

[Anynomouss]

@aglkm the path to the API secret appears to be correct:
node_api_secret_path = "C:\grin\contract_branch/wallet4_main\.foreign_api_secret"

@martinthonon The HTTP node listerner is started like normal

20250114 16:45:26.153 INFO grin_servers::grin::server - Starting rest apis at: 127.0.0.1:3413

[aglkm]

Are you sure that the API secrets files are really exists in "C:\grin\contract_branch/wallet4_main" directory?

I don't know what is the default location on Windows, but on Linux that's home directory: "/home/user/.grin/main/"

[Anynomouss]

I tried again today using the default wallet directory, so not specifying the top level directory for the wallet using -t .
Everything worked as expected.

Therefore I specifically looked at what happened when I did set the top level directory, since there must be a mistake there and indeed there is. It has to do with directories and slashes. When using the command
grin.exe -t wallet1 it will correctly set the paths to:

node_api_secret_path = "C:\grin\wallet1\.foreign_api_secret"

When I would for example specify the directory as
grin.exe -t wallet2/ it will wrongly set the paths to:

node_api_secret_path = "C:\grin\wallet2/.foreign_api_secret"

Using longer paths obviously also creates wrong settings:

grin.exe -t contract_branch/wallet3/ it will wrongly set the paths to:

node_api_secret_path = "C:\grin\contract_branch/wallet3/.foreign_api_secret"

Solution:
First parse the top level directory path given by the user, replace all "/" with "\" and replace all "" with "\", optionally trim any "\" on the left, depending on how the full path is constructed. I think the later substitution already is happening, the first substitution is not yet happening.

I will update the description of the error to match the problem. What surprised me is that the path is correctly used to create the wallet directory when running for example grin.exe -t wallet1/ init, it is only not properly stored in grin-wallet.toml and therefore only comes to the surface when running grin.exe -t wallet1/ info Because the wallet directory is created correctly, only the path in the settings is stored wrongly. This is extra confusing to the user since the path specified appears to be correct and accepted when initiating the wallet. Anyhow, it is easily fixed.
